Usually I have the patience to wait until the truth is revealed and the ML realizes how much he loves the MC but this is too much. At the point where he smashes your mother's piano, reacts violently, how can you still call it love? How can a small childhood memory match up to all of that? I do like to read, cliches and brainless plots sometime but this, this is a whole another level. I feel like the ML needs to be severely, severely, severely abused before there's even the possibility of them getting together. I understand that it's romanticized and over exaggerated but this MC truly has no self respect. Isn't love when you appreciate someone for the qualities they have? How can he cling to this "love" to someone who detests him so? At this point it's not love, it's a distorted obsession with that one childhood memory and one memory of him playing the piano. There, rant done.
This doctor totally feels like a love rival for Minato...at least I can see him falling for Shizuma
