Before I talk about the best worst thing about this series, let's talk about the actual worst things.

Watching this felt like watching something that should have come out 7 years ago, with all the engineers and their gears, the hazing and the "I don't like men, I only like you stuff", and they somehow made all this and more much worse than it should have been.

Even looking past all this, it's still difficult to enjoy because one or the leads is an absolute horror of a person. Essentially what we got was one of the worst male leads to ever grace our screens. He spends more than half of the series being a rude, abrasive guy who harasses his ex girlfriend, his friends, his juniors, anything that moves and breathes. They tried to give him a redemption arc, but too little too late to the point where you're going just end it, I don't care.
Couple this with another male lead who is just.. dull. That's it, his entire personality can be summed up with one word. One is a pushover, the other is rude, you're turned off by the personalities even before we can get to the romance.

There isn't much in that aspect either, a majority of the episodes is Prot pining over Pluem, and the rest is a bunch of misunderstandings that is resolved in the final episode. All throughout, I could not understand why these two even liked each other, and the acting definitely didn't help in selling their feelings for each other. As a couple, they had a maximum of maybe thirty minutes of romantic screentime. The rest was nonsense conversations, the male lead harrassing his ex, the other male lead pining (and failing because the emotions did not come through) from a distance, and Pluem bullying Prot.

I haven't even gotten to the best part yet. The factual inaccuracy.
They've apparently known each other for seven years. They met when Pluem was a senior and Prot was in the grade below him. The story begins when they're in their fourth and third year of engineering respectively.
Do the math, and it's four years.. right?
Nope, the show insists it's 7 years.

The best, best part though. The SUBTITLES.
Horrendous. Truly bad, I had such a hard time making sense of some of those dialogues. But so funny. Not as funny as some others I've come across, but definitely made the viewing experience a bit better.

It's weird though, because secret crushes aren't a new deal, and neither was this entire story, but I kind of feel like I would have enjoyed watching something along the lines of this story. They did not make it work though, none of it worked.
