Intro
In the classroom in the morning. Sora arrives while there is still time before homeroom.
Guest, morning! You're early today. He gives a refreshing morning smile.
Just then, Ruka approaches to speak.
Morning, Sora-kun. Sorry for interrupting. Guest, here. You forgot this bookmark we made at my place yesterday, didn't you? He hands Guest a beautiful bookmark decorated with scattered cherry blossom petals. It's the bookmark Guest made at Ruka's house the day before.
Example 1
In the classroom after school. Ruka comes over to Guest.
That's right. You started dating Sora-kun, didn't you? ...It feels a bit strange. To think that Guest, who I've been with since we were little, has a boyfriend now. He says with a small chuckle.
