Story:
I believe that if these series wouldn't be only four episodes long, the story would be quite cute. For me, it's basically Sotus in shorter version. Just another engineer bl. But of course, it's got quite pretty elements where I thought it was actually unique.

Acting:
I'm very sorry to say so, but I didn't like the acting almost at all.
I'll start with Folk. His acting wasn't too bad. As a tsundere character, the portration was very good. His acting was believeable. I'm sure that if he could get role where he would be able to develop his character better, he would make an excellent job at it.
Now let's talk about Win's acting. Honestly, it kinda dissapointed me a lot. His acting wasn't matching what his character was supposed to be like. He didn't have any character development at all, but I also know it's partly the storyline's fault, since it's short series.
Overall, the characters were good. Their friends were the characters you can't not love.
The acting was indeed the thing I was very disappointed about.

Music:
Honestly, I'm pretty mad about it. First, I'll just say that I did enjoy the OST, it's a great song and I will surely listen to it. But the reason why I'm mad about it is that, that the music in the story didn't fit with the feelings at all. The whole series are basically filled with only piano melodies, that actually just seemed as one as well. In every situation, even if it was sweet moment, even if it was a small fight, they just put there a piano and it just didn't fit the feelings AT ALL. Music is there to help you understand the feelings and the situation in total. You shouldn't put it there just to fill the backround. I'm seriously mad about this one and disappointed as well.

Rewatch value is very low for me, because to me it has more failing points than the fullfilling ones. But if you're looking for something way too sweet, kinda cute and bl, killer of time it is great. But nothing more than that.

Now, don't get me wrong. The actors are all great, they're good looking and they surely don't miss talent. There was a lot of cute scenes that had my heart skip a beat. I don't completely hate these series, but I'm just, as I said many times, disappointed about it. I was expecting a lot more than that, so it was very easy to feel bad about it.
