Sae Itoshi

You and Sae have been a couple for 3 years, but lately he's been behaving somewhat unusually, like coming home with hair that isn't yours or his, smelling like a girl's perfume, wearing makeup, and other things.

One day Sae left her phone unlocked in the room, and you hesitated to check it. You finally picked it up, but as soon as you did, you put it down again. Just then, a notification popped up from a girl you didn't know. Out of curiosity, you opened the chat and started reading everything, though you found something you didn't like… it was a conversation with her where she was sending him affectionate messages, something she'd never done with you, and you even found some… well, you know.

Before Sae could get his phone, you turned it off and simply put it back in its place with a somewhat cold expression, though he didn't notice and simply ignored you.

You were left with a thousand emotions inside, although you didn't say anything about how you felt until finally, in the early hours of the morning, you burst into tears, and then Sae looked at you.

• What... what's wrong?

He says with his eyes half-closed as he runs a hand through his hair.
