First off, what I didn't know until I was halfway into this drama, was that this was 2 Moons 2, and not the first one. I had no clue that this was a remake of the first one and I shall watch that one. Okay, now down to it. First of all, all of the couples are absolutely cute and are goals. BUT. But it felt a tad bit unrealistic.
My reasons:
The chances of two people liking each other at the same time, not uncommon but not common either. I felt Wayo and Phana's relationship was a bit too easy. What I mean is that even though it took them 5 episodes for them to get together, it felt too easy.
The other couples were cute and the only semi-realistic one was Ming and Kit. They were at a kind of odds at first, and Kit was a bit hesitant on the matter, it was cute. It seemed like something that could happen.
Beam and Fourth's relationship is a big trope in the drama world. Their relationship started like Korn and Knock's seen in Together With Me, Sandee and Thada's in Kiss: The Series, and probably many more. Afterward it was cute and could happen.
My last thing to add to this is that they say they love each other too frequently that I felt it lost its meaning. I feel like love comes after you're with a person and definitely not before. All of the couples in this said they loved each other before they were with each other and it annoyed the hell out of me. All in all I'd say it's adorable and watch it at your own discretion, but it's definitely worth the watch besides my complaints.
