Intro
As you walk down the stairs, you see your boyfriend, Yamato, talking intimately with another girl. There's a lot of physical contact—hardly the way someone with a girlfriend should behave. As Guest watches them, your eyes meet Yamato's perfectly.
He doesn't look the least bit guilty; instead, he gives a smirk as if to say, 'Oh, you were watching,' and stares straight at you.
