first i want to say, this show is DEFINITELY worth the watch.

to address concerns ppl have made, heres my take on them:

~~
lin yiyangs comeback to billiards, why didnt he struggle?
i think thats mainly due to a couple things. 1, he is a supposed genius. learning from a very young age, and competing and winning at a young age. 2. even tho he retired, he still kept up w the sport bc he loves it. he trained daily, owned a billiard room, and if yall forgot, he knew who yin guo was bc he was probably watching games. (in the beginning he had a pic of her playing from a game)
so if he is still knowledgeable, and trained, he wouldnt struggle. billiards is more so like chess, its based on moves from the table. so as long as he can get the results he needs to get points, he wouldnt struggle.

their kinship, ie, the FL shying away from his kinship.
some comments were like shes annoying, its been three years. 1. i think yall forget the age difference. 2. yiyang had no problem in showing PDA, but its obvious yin guo did. 3. in the beginning wouldnt yall be like her? they have been dating for years, but cmon now, theyre not together every single day, i would be shy too. i mean in the end even in her moments, she said she felt shy seeing him bc they were apart for so long. once theyre together when he comes back, i can see how yall would want her to accept more kisses and stuff, but like i said shes not into PDA. after all, her relationship was a secret from her family, she felt odd being physical around their team bc its their team, and hes already ranking, becoming the caption and leader of the club... while shes a rookie. i think she was supposed to genuinely feel shy abt their standings and their age difference. and in the scenes where they were alone, i think its bc shes shy abt where it would lead, bc ngl i got the feeling yiyang wanted to ... whenever he could lol. and it adds some spice to their lives. accepting every single kiss isnt mandatory, and whenever she rejected it, his face gave (to me) "omg i want to kiss her even more" like it couldve been just me but thats the face i saw on him. kinda like a "really? rejecting me? i want to kiss you so bad..."

comparing it to hidden love... weird.
if im being totally honest, these shows are the same. they focus on the main leads romance and relationship over any real problems. and any problems are solved fast, or are due to a misunderstanding thst ends up resolved w no real hesitation. the leads dont have major struggles and for the most part have no toxicity in their relationship. as a long time c drama watcher, these shows are very similar. so its weird that some are comparing it to hidden love and saying its worse than hidden love.

yin guo and yiyang are an unproblematic couple. they both knew they were the one. amd were willing to go through anything together. they supported each other until the end, and gave the other everything they could. whether its just company and support, rankings, advice, love... just whatever they could offer.
this isnt a dramatic love story, not everyone has one. i think yall forget that. not everyone has an opposing family that does whatever they can to stop the relationship, or an ex that wants one back. some relationships are relaxing, simple and easy going like this one. it was real. thats why i liked it. bc if i think abt if this were me, my relationship would probably be like this. no real drama, no opposition, just going through life together. not everyone needs to be separated 10x, going through hell and back to realize they found the one. romance isnt like that. romance can be hard, but romance can be simple. and yiyang said it himself, he would adapt to yin guo. and he did, bc he loved her and he knew she would be his wife one day.
