It's not similar except they're both sports manga and the manager/athlete thing. The personalities and tone are completely different.
They have similar plot points, its very blatant if you've read the novel. If melting point was an omegaverse it would be even more blatant.
A lot of stories, especially romance stories, have similar plot points. It's the character, their dynamics, their supporting cast, the execution etc etc that allows them to stand apart. The couples have completely different vibes and that's a good thing.
Isn't it a little weird how similar this is to the novel/manhwa Dash....?
