I don't really need the green haired guy and the purple haired guy's story tbh, frankly the former is just mean spirited. Also, I like A as his own character but his relationship with Yu Ai is just lackluster, and I know they're not blood related that's not my issue.
I love this story so much that it pains me, figuratively lol, to be aware of how much I roll my eyes whenever the said characters show up.
