It was so cute! Kind of heart wrenching since Miyanari didn't expect Hashiba to return his feelings but aaaa. I just kinda hoped more about the red strings but it's good and fluffy.
Plot: One day Miyanari saw red thread connected to his pinky finger, leading to his classmate that looks like a delinquent. From thereon he find himself crossing paths with Hashiba, from the elevator, in front of his house and learns that Hashiba wasn't the delinquent that he is. With that he falls for him and confesses, the thread being gone because he can't see it anymore. With the confession, Hashiba was sure to think about it carefully. He was confused as to how can you consider someone to be special. He kind of wished he could see the red thread and he did but it's not connected with Miyanari. However he still confesses and everything worked out in the end.
