Their relationship is toxic. They've broken up and gotten back together again and again for years, Ugetsu (the violinist) would have other partners and Akihiko (the drummer) as well, they were hurting each other because they couldn't let go. Aki was obsessed with Ugetsu's music, with his sensibility and Ugetsu liked that Aki was able to put up with all that. But that it's not healthy. I guess that's why Haruki was viewed as "the saviour". He was simply there when needed and never asked for anything in return
Their relationship is kind of like the lyrics of the song: seesaw by suga (bts)
isn’t the violinist and the drummer guy together? Then why does the drummer need to be “saved” by the dude with long hair?? Like what’s the problem with their relationship if they like each other?(〜￣△￣)〜
