I have very mixed feelings about this series.
From the beginning I knew the humor of the series will be too cringy for me, but I was ready to put up with it, because I really liked the plot at first.
I instantly fell in love with Zee and I already knew from Love by chance that Saint is good actor, so I was on board with Fighter/Tutor couple. They worked well with Fighters confused emotions and it made the storyline very delightful to watch.
On the other hand I didn't really feel the Saifah/Zon couple. I felt like Fighter/Tutor really outshined them with their chemistry and more interesting plot.
Till the episode 6 I was thinking that this may be one of my top BLs, but boy, was I wrong. After that the things started to go downhill. Everything got really messy and it felt rather draggy. I started to feel the urge to watch it at 2x speed and most of the time that is my red flag.
Nevertheless, I decided that I'm strong and I will watch this till the end. Ooof, but they really do know how to test my patience.

I feel like they were trying too hard to please the viewers and because of the large amount of those "fluffy" moments the storyline was really dull. They lost the balance between cute, repetitive moments and clever, naturally flowing storyline.

After episode 6 I partly lost interest in Fighter/Tutor, because it started to feel kinda forced and kinda cringy (and not in the cute way). So to my surprise Saifah/Zon creeped into my heart and became my WHY R U no. 1 couple. But then Coronavirus just casually said: ,,Nah, girl, you don't deserve this, Imma just take them from u real quick, bye."

Episode 9 really brought up the worst in me. I know that it was partly because of the pandemics, but they were really unprepared for unexpected situations. I get that they tried to get the popularity and stable fanbase by airing the series earlier then the others, but they weren't ready at all. I was thinking that I have to be nicer, because they were having issues and it's not their fault, but why is it that other BLs airing at the same time do not have such problems as WHY R U?
Okay, back to the breaking point. Ep 9 was really just montage of someones cheesy trip without any story progress whatsoever.
I was like ,,okay, I can take this. They will redeem themselves in the next episodes." But guess what? Episode 10 was even more storyless beach montage. So that is about 3 hours of beach content if I also count the last episode (but I forgive them, because in the last episode there was atleast Saifah/Zon). So my question is: did I watch thai BL or travel agency ad? Like I'm genuinely not sure at this point.

Also they made the hot and heavy scenes really repetitive. In other BLs I'm most of the time wishing for more passionate scenes, in WHY R U I was thinking if they ever do something else. Like could you stop for a moment, you rabbits???

And what was this evil korean mother bribing twist that Fighters father pulled off?!

The way this series is handling every problem feels very forced and unrealistic. I don't like how they force a problem to occur and then force it even more for it to quickly disappear. I mean don't even create obstacles at all if you cannot even execute them properly. It's really stressing me out how easily HwaHwa or Fighters dad change their minds just for the sake of the happy ending without any obstacles for the main couple.

The actors had overall great chemistry, the acting was also alright and they made it somewhat watchable.
I don't know what to say about the plot. They had some interesting ideas, but executed them terribly. Also in the half of the series the storyline is completely nonexistent. It's like every episode is the filler episode (with a few exceptions).

It surely isn't the best series I've seen, but it also isn't the worst. Had potential, but didn't fully used it, rather wasted it.
