Ai is such a child. It's amost annoying the hoops he leaps to to come to the exact wrong decision. I'm only on ch 3 but he's got it in his mind that Okumi is bored with him and doesn't want to stay with him from the fact that he called him multiple times throughout the day and ask about his friends and plans...like wtf.
Just saw that there will be a vertical adaption of this, and its supposed to come out on October 8th. Looks like a reread is in order.
