Ernie Romelo Phunnoh an Ohmmick will happy a happy ending as for EarnPete, and Mawin (or Perwin?), I doubt it tbvh. Especially with the later there was a reason why Win broke up with Mark in first place.
I think Per and Win will end up together. Now i'm just speculating here, but i think Mark might become too obsessive over Win. As for Earn an Pete, i have no idea.
I completely agree, that's why I want him to be as far away from Win as possible. His love, their ex- relationship was sickening and unhealthy, to the point where Win compared him to his abusive father and can't forgive him. How could they end up together? He isn't nice nor sweet, he is manipulative, possessive, "abusive" and gets too easily angry if something doesn't match his taste. Win deserves better than him.
PerWin ended up as friends right? So I'm thinking maybe there's still a second chance for MaWin. But I doubt they will end up together.
