I don't think so. The manga is just to short for him having so much playtime. Maybe for the last chapter, too see a happy meeting with the four of them. We all know Koichi is the right one for her.^^
It's no problem, as it all seems to go smooth right now. I want a happy end and it looks like we will get one. A more clear one than in Hana Yori Dango at least.^^
Don't be sad, just read her next Manga Matsuri Special. A little bit more masculine, but not less funny and good, if someone actually did scanlate it. *sad*
Takai said: i will die from shock and disappointment if she -doesn't- end up with Kouichi o_o;
. . . She doesn't! [yeah right.] *cries* [Denies the fact that they are perfect for each other] He, he should stay single! Forever! [If I can't have him no one can!]
