Due to this thread, I took out the set and re-watched the last ep of the series. (It was really sweet as usual.) The OP for the ep (which is a different one from the earlier subbed eps) shows a young man with light brown hair sitting with a bouquet next to him. He (Minoru) was reminiscing the past when the two girls fought over him. And at the end of the OP a girl came and met with him but they didn't show the face. Gee, this makes me so curious to know who the girl is. Looks like it's time for me to collect the manga too.
