Mishounen Produce
Two childhood friends from the boonies plan to take their school by surprise: she wants everyone to see him for how great he is and not just as a country bumpkin. She does the job too well and soon enough he becomes a sensation in the entertainment business.
Last Game
After 10 years of chasing after her, Mr. Perfect's finally acknowledges his feelings. All he has to do is to get Ms. Dense to notice him. Great love story, I love that it didn't just jump into things but you could really empathise with the struggles of one-sided love. Kind of wish there had been no time skip, but it was still quite fulfilling to see them get married (:
Katakoi Triangle
Adolescence means getting to know yourself and learning about feelings you might not quite fully understand. Things will get a bit messy, maybe people you thought were close to you end up being less important than you originally thought. You might even meet completely new people, who just turn your conceptions upside down. Just gotta hold on to your core, be honest, and accepting.
