Does anyone know any manga like this where the main lead regressed and knows what happened...

not manhwa, but manhua/danmei novel called 2ha (dumb husky and his white cat named shizun) - just pay attention to the tws first

There is another one called Dead Man Switch. Zombies in it though lol. But same premise where mc doesn't know the previous life and the main lover does, and is trying to protect him etc.

Thanks!
