With that kind of declaration, Satsuki stood up, folded her sleeves that revealed her lean arms as she marched off to the door like a soldier ready to take down a dragon.

As our attention was all focused on the ruckus being made beyond that door, we watched the slightly comical confrontation between the two sisters.

What? I told mom that were not to be disturbed. And you just did.

Upon opening the door, Satsuki stood tall and glanced down at her sister thats at least half a head shorter than her. She also slowly crossed his arms to add an intimidating presence.

Although Satsuki secretly admired her sister, what the latter was doing this time most likely passed the threshold that she could endure.

Even if her back was turned to us, I could imagine that girls dark expression coupled with her cold-looking eyes glaring at her sister who had an amused smile.

Mom left to buy something, you see. Cant I at least check on my dear lil sister? Her sister replied.

Because of how Satsuki was standing at the door like a gatekeeper of sorts, I couldnt really see her sister standing in front of her. But just judging by the tone of that voice, its filled with mischief. Shes even giggling at Satsuki.

Satsukis shoulders started trembling, clearly restraining herself to lash out at her sister. Even so. That doesnt give you the permission to come and disturb us.

Not taking any hint from that, her sister, Setsuna, continued. Hmm? When can I disturb you then? Is it when you and Onoda-kun are on the bed?

Wha?! Y-you! No! Satsuki instantly panicked. She stepped out of the room and hurriedly pulled the door close behind her.

Thats clearly taking it too far. Even I wouldve reacted the same, especially when theres someone here thats unaware of our relationship.

And as expected, the girl I was pertaining to confusedly muttered. Eh? What are they? What was that about, Onoda-kun?

Aya was quick on the uptake. She promptly moved to Kanzakis side before I could respond. The girl then sent me a small gesture that said to leave it to her.

I nodded to that but I thought that I should at least answer to clear her doubts. My gaze also passed by Sakuma. The guy instantly nodded his head, his mouth closed shut.

Its great that hes not slow this time.

Ah. Perhaps because Sakuma isnt her boyfriend, her sister thought that theres something between us.

Same as usual, I neither denied nor acknowledged our relationship. Subtracting Satsukis initial reaction or even if that was included to be interpreted as the girl being embarrassed by it, Setsunas words could be taken in as an assumption.

You three stay here. Ill have a look. Its not everyday to see Maemura that embarrassed, I somehow want to witness that. I intentionally laughed for Kanzaki to see before standing up and approaching the door.

Surprisingly, I hadnt even reached the doorknob yet but their voices could already be heard again, especially Setsuna's unrelenting mischievousness.

Oh? Judging from your reaction, you two have done it already. How nice, my sister grew up to be a fine woman

Nee-san Can you shut up for a moment? Do I need to use violence here?

Heh, youre not going to do that. You love your sister too much.

Her sister was clearly so used to Satsuki that even if she raged in front of her, it had no effect on her older sister thats dead set on playing with her.

I might just change that if you dont stop, nee-san. Are you really going to do this? Dad is downstairs.

Nope. I want to tease my little Satsuki. Also, you have yet to properly introduce him to me. Like you promised.

If thats what you want, Ill call him

So, thats what shes actually aiming for, huh? To get to know her little sisters boyfriend.

At this point I was already before the door, I only needed to turn the knob and I would reach Satsukis side.

Without waiting for her to turn around and open the door to call me or hear her sisters response, I opened the door and stepped outside before closing it behind me once more.

You dont have to call me. Im here Uh, Onee-san. I might be out of line here but can you stop with this?

Oh! Great timing, Onoda-kun. Stop what? Teasing Satsuki? Are you also angry that Im bullying your girl?

Id be lying if I said no. Its infuriating to see her teased like that

Im the only one allowed to do that! Well, theres no point blurting that out.

Is it that fun to tease your sister?

Of course! Ill be leaving soon so Ill make use of this time to dote on my cute little Satsuki.

So, its doting now instead of teasing? Judging from this short conversation I had with her, thats a halfhearted answer. Its in her nature to tease. Thats how she was even when I first met her.

The question is from the stories I heard from Satsuki and Sakuma, shes not originally like this It looks like she changed over the years, huh?

On my side, Satsuki clicked her tongue. Not convinced with her sisters answer. Perhaps, if I wasnt next to her this time, shed lash out again about her sisters behavior being nothing close to doting.

Anyway, looking at Setsuna like this, shes clearly not someone Sakuma could handle and despite their similar facial features, Im kinda irked by that wide mischievous grin on her lips.

Thats some tough love, onee-san. But I guess I can understand you. Shes going to go back to college. And if shes telling the truth then doting on her little sister in this way was somewhat understandable. This isnt the appropriate place for that kind of introduction so can onee-san wait until were done with our studies?

You You dont have to. This is enough for introducing you. Satsuki instantly reacted, her eyes clearly telling me that its not a good idea to be involved further with her sister.

From what I observed, shes not going to stop. I hate to see you looking troubled. Naturally, I wont go alone, accompany me later.

More than acceding to her sisters request, this was all about not wanting to see Satsuki in trouble.

Hmph, youre the one deciding this but youre going to drag me.

Do you want me to go alone?

Absolutely not! I Ill only be going to make sure nothing else happens, alright?

As expected, thats just this girls nature of being a tsundere. Whats going to happen anyway? Id choose her over sister anytime.

Then its settled. I smiled and hugged Satsuki right in front of her sister who already turned speechless from what she just witnessed.

And right at that moment, a shadow approached from behind Setsuna.

Its her fashionable friend, Juri whose eyebrows were twitching in annoyance as she grabbed the girl at the back of her neck like a cat. Setsu, you mischievous imp. Stop teasing your sister and lets go. No wonder youre not coming back.

Upon witnessing that, it seems that Satsukis sister isnt that tough at all.
