So this may sound extremely vague but it's literally all I remember. And it's been in my memories for so long but can't find it. All I remember is that it's sort of like 2 families that have some sort of power. And it's like fallen to 2 guys who have to win against the oth and the only way to win is in a kiss or something. And they constantly kiss and fight. They're not gay in the beginning but like always they do at the end lol
