While watching the first episode and seeing who were the main characters, I immediately started guessing what would happen in the story. I expected the usual clichés: the main guy with glasses and a goofy smile would get a makeover and suddenly turn conventionally attractive, his panicked friend would get consistently (and uncomfortably) hit on, and their feminine friend would just be the comic relief of the show. Anyone's stalking or harrassment would never be addressed and the bad behaviors would be just romanticised. If it wasn't for the countless positive comments on this page saying that this show is actually good, I wouldn't have been able to keep watching.

In the end, all my expectations were destroyed for the better, which I guess says it all about how actually good this show is. The usual tropes were subverted, making the series a lot more interesting to watch. After feeling a lot of second-hand embarrassment for some ridiculous scenes at the beginning of the show, I got so invested I finished watching everything in the span of a few days. The actors were all amazing and I really hope I'll get to see them again in other future projects.
I also want to compliment the translation team, because the subtitles were some of the best made I've ever seen - providing not only the translation for the dialogue, but also captions for sound effects, and context and cultural information about what was going on at given moments.

I recommend watching this one at least once!
