After Zen lets himself get beaten up to save Risa from Fuumin's gang, Risa realizes that what she feels for him may be real. But while the two are closer than ever, Zen struggles-while he knows Risa cares about him, he's not sure if she sees him in a truly romantic way. After all, it's hard to tell if her heart races like his does when they're together when she's always falling asleep around him! Meanwhile, an old middle school friend of Zen's transfers into Risa's school...and she still has a big crush on him.
