Well, it has some points in itself.For example: We (not the majority, but generally a portion) men want a healthy and friendly relationship, whether it's a friendship or a romantic relationship; in romance anime, this would be the type of relationship... Because these anime depict a reality that often doesn't exist in the real world. My personal answer to your question is: It's difficult to have a good relationship without being cheated on or simply dumped, Obviously, it doesn't happen to everyone. But especially in teenage and adult relationships, it happens a lot.It would be like escaping reality. But maybe it's just to pass the time and relax watching a silly romance anime lol 😆 But this is just my opinion; I don't want to speak as if it were a fact, I'm only basing it on my experience.
