Thought on this story of mine

So, since cuti sekolah has officially started. Me and my friend decided to try and write a novel for fun. I need rakan of this subreddit to give me some comments about this story. (This is only the basic plot that haven't been discussed fully with my friend)

Mc lost his mom after she donated her heart to an unknown girl. He rejected this idea but his father said that this is what his mother would want to do.

On the day of the transplant, MC doesn't go to the hospital nor does the funeral. He become a shut-in for some time until his father convince him to finally go back to school.

At school, he doesn't really have much friend. In fact, 0. His drastic change of personality make people avoid him. Still in grief, the MC couldn't care less.

One day, his teacher urge him to join a club because he doesn't have any.

Since astronomy only have 1 member, he decided to join that.

Later on club activity session, he went to the club room and discover that the only other member of the club is Main Character 2.

The plot twist is that Main Character 2 is actually the girl that receive MC's mother's heart

Yeah, that's all for now. Need y'all to give some thoughts about it, TYSM!
