Love it

Read again the first manga and this adds something nice to Aoba's character, I do think in first manga he is purposely written a tiny villanous so it pushes you further into the main couple, but in a bigger picture, he never understood his own feelings neither Miki's (￣∇￣")

He was confused but nonetheless he is Miki's friend, he likes Miki's presence and felt lonely when he wasn't there, he tried dating other people to see if the feeling was similar but nothing really sparkled like Miki for Aoba ╥﹏╥ he thought "It must be love, but I don't want to possibly part ways with Miki if we make it official and later break up" so he tried to keep close to Miki, and thus making him manipulate Miki's feelings, feeding them when it was convenient so he would always have Miki by his side without the responsability that cane with dating and Miki's feelings and then everything BOOM happens and he respects that Miki moved on and found someone who can love him and reciprocate his feelings (≧∀≦)

And Aoba was left, well, lonely, because he wasn't Miki's number one anymore, obviously now he could have started this friendship/fake relationship with the dude (bless his soul he is my baby) out of convenience to get out of the loneliness Miki's fault made him feel, but at last, he found some love, and that is pretty nice, sincere opinion, Watarun is a nice guy, and I like him plenty, it is infuriating to think he manipulated others to not feel bad himself, but it is a dramatic fiction, and I think he realized it soon enough, and he is very different from first manga, reality check hit like a truck (づ￣ ³￣)づ love you Watarun!!!
