The sisters were nice to him but it seems they only didn't get mad because he is a guy .. i wonder how they would've acted if sena was a girl instead it seemed like they viewed him as competition or something when they thought he was a girl
Guys they couldn't make it gay because the only way for her to come back would be as her daughter. They are soulmates they complete eachother and it not being in a lover way doesn't mean its any lesser than what they have now
Oooo i like the idea of them together now
