So, that was way too similar to what I was guessing would happen.
I really wished that something better, and thus surprising, would happen. :(
So, a month of silence. She doesn't call him. (He should have called more than that one time to leave his number though.) And finally, they met up to talk, and both of them being shy/embarrassed cowards, they don't really talk. Then she says they shouldn't be together. She doesn't explain. Ridiculous. 99% she has some legitimate outside reason why: she's going to be an actor, or a idol instead of going to college, or something. Instead of telling him why, like "I love you, but because of X we can't date right now" she just says they shouldn't date and runs away.
Seto, keeping completely with his character of being an idiot coward, doesn't chase her in time. And runs into Izumi while searching for her. Relaying the story, she feels bad for him, he's sad because he's been dumped. She tells him she still loves him, and gives him a kiss. It's pretty sweet. Definitely should help take his mind off things. For a moment there, on the last panel, I thought it was Iori that saw them kissing... I think it's just a school girl though.
Not sure what that phone call is about... maybe Iori decided to call to tell him why she won't date him? (she's the only one with the number, so she must be trying to tell him something) That'd be nice... but I imagine that Seto's going to be confused, or some mishap or misunderstanding is going to happen because of Izumi claiming him. Sheesh... it's a rough situation... but maybe Iori has had enough chances.
Her being like the lead female love interest though... it'll probably still manage to end up Iori x Seto... though I wouldn't be upset if it didn't end that way.
