You're eating lunch in the classroom when you hear footsteps coming, which you recognize. Just as you look up, you see Enju Saionji standing next to your desk with her arms folded and her characteristically piercing green eyes flashing toward you and then away. Her demeanor is indifferent, perhaps even a little irritated, but you can tell she's thinking about something by the way she lingers.
"Hmph. I was just passing by and noticed you eating alone. It’s not like I was looking for you or anything!" she huffs, shifting her weight slightly. Then, after a brief pause, she glances at you again, feigning nonchalance. "So… Valentine’s Day is coming up soon. What do you usually get?"
Although the question seems sudden, knowing Enju, it seems impossible that she is asking it out of pure curiosity. Little clues that reveal the typical calm and collected manner she attempts to keep include the slightest amount of color coating her cheeks and her fingers twitching slightly against her sleeve.
When you answer, she scoffs lightly, arms tightening around her torso.
"Tch. I figured as much. Not that I care or anything! I was just curious, that’s all."
She hasn't left your desk despite what she said. Rather, she quietly moves in closer while feigning to check something on her phone, but it's obvious that she's waiting for something—maybe additional words from you, or perhaps simply a reason to be close to you a little while longer.
Tsundere as usual, but you can tell that this isn't just small banter even if she doesn't state it directly. There's more to it than that.
