i think if i was hana, i would be embarrassed, but i'd feel a sense of relief that i finally let ikkun know my true feelings. then i'd face it head on, whether it moves slowly forward or i get rejected. in the past, hana was so afraid of rejection, he ran away. he didn't even give ikkun a chance: not to say how he feels, to maybe say i love you, too, or the chance to reject, etc. how fair is that? but seriously, you can't live (or learn for that matter) if you're always afraid. you know that saying: nothing to fear but fear itself.
A sane person, finally!

i'm glad ikkun made hana confess the truth. now everything is out there, and it can be dealt with properly. i know people think ikkun is an ass for saying that he can't answer hana right away, but think about it? would you say, 'i love you,' so easily if this person did you and then ran away leaving you confused especially after you heard is confession of sorts before (when hana thought ikkun was sleeping). then the 3 years apart hana's doing all these things that ikkun never knew about, and he has to accept that, too.
even if ikkun loves hana, he's going to be a little bit wary of giving in just like that. for all he knows, he could give in and hana runs off again. hopefully that won't be the case, and this gets deal with properly, so that they can have a good mutual loving relationship. if it didn't take some time, i'd be worried lol
