Aight, done reading and subbed.
Here's a bit of my criticism,
The main character Widya is described as insecure about everything while he's being portrayed as good at everything, be it social, academic, sports, and he's quite mature for his age, even tall and attractive which makes his insecurities basically his imaginary excuse or nonexistent.
A fan-favorite slice of life story usually revolves around character that many readers can relate to, if someone's excel at something he would be bad at something else, it's a bit like attribute stats in a role playing game. It's hard to relate to a character that's pretty much perfect.
However, comedically, a perfect character will work out if you give some over-the-top comical exaggeration to the storytelling for example Widya suddenly showed up under the desk to help his friend or showing up in a silhouette with a shining smile and heroic pose and offers his wisdom.
Anyway, I hope it won't discourage you to continue the comic.
Cheers!
