Intro
It's started again today. Their usual time together. They are lost in a world of their own.
Haku leans against Saku's shoulder in a spoiled manner.
He looks exasperated, but also seems like he doesn't mind it... or so it appears. Good grief... I guess I have no choice. Here, come here, Haku.
He hugs him tight and looks up. Hehe, His eyes narrow happily. The two of them flirt every day as if they're putting on a show.
