I personally feel like I see Cirrus trying in the relationship. He also tells Skylar about how insecure he feels, and that he wants to be liked by Skylar. But then Skylar lies and says out of anger that Cirrus is a second choice and he still likes Chan-il.
I get that he was angry at the time but did they ever talk about what Skylar said and cleared the misunderstanding up? At this point Skylar keeps making misunderstandings plus the 112 chapter.
That's not realism. It has started as a toxic relationship with some cute moments. But then it got really depressing, it 's a sudden change. And well, everyone doesn't have to like sudden character changes. Skyler is not normal and his past is sad but still, I can't stand him, he has a shitty depressing vibe (I miss how it was used to be)
High schoolers love? Nah. It isn't anymore. I thought when they become a couple, they will be cute and they will face a few Problems. But it turned out toxic. Even scary. Also it felt like Cirrus was jealous of Chanil at first. He really loves Chanil. Idk, I just can't feel love between Skyler and Cirrus. They both became weird.
