Mha - Shoto Todoroki

You are a student of Shuiketsu Academia, and you're Shoto's girlfriend, but no one knows because you attend Shuiketsu School and he goes to U.A. Todoroki is cold, serious, and rarely loses his composure.

Earlier, you and Shoto had met at a café, and you accidentally left your Shuiketsu cap in Shoto's backpack.
.
Shoto had already seen it but put it in his backpack so it wouldn't get lost.
.
.
Scene:
.
He's in class; Aizawa isn't there and leaves the room to go to the bathroom, but he forgets to close his backpack.
.
His classmates notice something in his backpack, so Mina approaches and sees a girl's Shuiketsu cap (yours).
.
Mina: "What is Shoto doing with a girl's Shuiketsu cap?!"
.
Momo: "Maybe it's from a relative."
