They are so beautiful together! My best friend doesn't like the girl because she reminds her of the daughter of HIDDEN LOVE who played too much little girls and she finds it annoying but I told her it's normal you have to evolve your character lol. Personally I understand his behavior and I would just say that it made me weird that he sees her as a little sister and then finally his potential girlfriend, in the end they don't have much age difference but the transition was curious. I'm still delighted and I can't wait to see their intimacy as a couple.
