after everyone from the sea came back. Tsumugu finally made a move on chisaki. chisaki liked hikari but manaka and hikari are going out.
Tsumugu wanted to ask her after he had all his research done from Tokyo. but when tsumugu came back to greet chisaki. was with a boy and chisaki said "welcome back Tsumugu this is my-" and the boy stopped her and said "hello I heard a lot about you my name is Zen " *whispered to his ear* "I'm going out with chisaki" tsumugu believed him and went back to his house. chisaki said "bye tsumugu I'm going to my place" (chisaki moved out and became a nurse) tsumugu went to his room and sighed he didn't know what to do now. and he thought that Zen seemed a little suspicious and after that he stalked him a little and figured out that he was cheating on chisaki with 2 other girls. as soon he knew he went to tell chisaki. once he told chisaki she busted saying "he's not my boyfriend he just a patient that wanted some fresh air". tsumugu went in his knee and laughed to. tsumugu thought it was a good timing because she was in a good mood so he said. chisaki I love you will you go out with me. chisaki started to cry and smile and said "sure" and hikari and manaka and everyone else was there hiding and said congratulations. and after 5 years tsumugu and chisaki got married and had one gorgeous daughter her name was tsuki.
the end and I'm very sorry for the grammar errors
