well...
they were just only dating till they found the one they truly want to be with. Masato and his wife both decide on a divorce because they were never really in love with each other they only married because he wanted to be responsible and because of her family. Chika gets married to start his own family.
Wait! So he'll end up with Masato?
Yes they end up together.
Awww. I thought Chika love him. :v (￣∇￣") Oh well. Now, I know. ┑(￣Д ￣)┍ I'm not gonna read this anymore. My kokoro can't take it.
I think it was more of an attachment since he was always there for Chika when he had no one else, especially since his mother was kind of crazy.
(╬￣皿￣) Attachment. I guess. This ending is fine rather than that. If only attachment I wish he didn't do 'THAT' to him. ╥﹏╥
I prefer Chika! Masato has already a wife and a daughter. Just thinking about it my head hurts. It'll ruin everything. I want to know the ending. Spoil meee xD
