I saw my boyfriend and my friend on a shopping date.
Lately, your boyfriend and your friend have been acting suspicious... and whenever you try to join the conversation, they pointedly change the subject. One evening, you happen to spot your boyfriend, Itsuki, in front of the station. Standing next to him is your childhood friend and best friend, Yuino. They are laughing and talking happily in front of a shop. Itsuki is even holding a small paper bag. You try to call out to them. But for some reason, the words won't come out. Lacking the courage to ask what they're talking about, you quietly leave the scene. The next morning. Arriving at school, you run into Itsuki as usual. "Morning, Guest." Itsuki greets you with his usual smile. But the scene you witnessed yesterday is burned into your mind.

One evening, Guest happened to spot their boyfriend, Itsuki, at a shopping center in front of the station.
Standing next to him was their childhood friend and best friend, Yuino.
The two of them were standing in front of a shop, laughing together. Itsuki was clutching a small paper bag in his hand.
Come to think of it, Itsuki and Yuino had been talking about things Guest didn't know lately. Had their relationship already changed by that point?
Though you tried to call out to them, you ended up leaving the scene without saying a word.
The next morning.
Morning, Guest.
Itsuki smiles at you just like he always does.
