overall, mine seem to be differing from most opinions here BUT I am going to stand by it. Gen Y is a really good show.
Very personal opinions, here we go.

# STORY: Normal series, romance only, no moral take-aways. WRITING at times is a mess.

✪ Minus side would be how haphazard the plot inclusive of WAYU is, almost as if the writer feels conflicted in every two episodes on which pair to go forward with. Not to mention new plot-twists were added in last couple of episodes. It was indeed bearable but almost amateur-ish move.

✪ On the plus side there are no major plot-holes, the subplots all relate to each other and despite having multiple supporting characters they are almost well managed.

✪ HUGE appreciation -
>> no non-consent being romanticized in any way (the few "physical" scenes were all within a safe gray zone imo), consent is unfailingly given importance.
>> they stayed away from "wife" tags for love interests / boyfriends
>> at the core characters are no pushovers,
>> there are no sexuality tag discussion - it was almost a pan-normative zone, and anyone could fall in love with anyone.

✪ Not only is it made in the right way, this was a naturally unproblematic show - it did not really bother to project the correctness. It was subtle and weaved into the nature of the show. Personally I appreciated the lack of implicit mocking of other series (even if they had it coming) to show how politically correct this series is- that is something few pretty good series had done, which made me slightly uneasy.




# ACTING: Kimmon-Copter just floored me with their acting, they were pure talent - I might have extra love for them after being rescued by their scenes after having to watch the other, stiff, couple. Hate to be criticizing a skill I do not possess but Dun and Bas just .. are not the best of actors. The engineering senior gang is also teeny bit awkward at times but again, way more natural. The high schooler gang was breath of fresh air, loved how they can bring the energy up.




# CHARACTERS/ COUPLES::

✪ MARK & KIT - Seriously sweetest dream couple. Realistically such a couple might not exist but then, that is the reason I watch dramas. They are patient, understanding, do not stress unnecessarily much on ego, and not to mention truckloads of sweetness and love - couldn't get enough. Personality wise, I cannot help but think how suitable these two are for each other. Mark is someone who can get to emotionally guarded person like Kit. And Kit does deserve the world. My favorite character indeed, wholesome, caring, understanding and mature - I just feel supportive and protective of everything he does <3

✪ WAYU - not been a fan of the actor himself but the character seems okay. Did not find him clingy or weepy or dull or depressing, he was simply a person who was deeply in love who got his heart broken.
THANU - again, not a fan of the acting, character being confused seems justifies to me though. Got no complains about his actions.
PHAI - sweet, and angelic character, the actor's looks almost suits that. Love how mature he is and pleasantly happy about the plot making two brothers have similar core characteristics!!!
SANDEE - confusing, but lowkey trusting him
TONG/POK - Surprised but sudden burst of chemistry, definitely second favorite couple!
KOH/JACK - probably 3rd favorite couple. And they are not even a couple :)
