Take away sex.
Add romance schemes, diabeetus, fluffly and immediate relationship resolved in thirty seconds.
Here you are Tsurezure Children.
No story, no real character development outside their love story, no particulary funny reason to laugh.
Romcoms work if charachters are relatable, grow up, you can be happy or sad for them. Here there are "General sport guy A" meets "General deredere B", or "General geek C" is loved by "general shy girl D". A big meh.
Yes, there are some "smart" choices, "Tsurezure Children" show us lots of types of confessions, first kisses, friends helping each other in love stuff, even real unconventional ones... But... It's like a big catalogue of love stories. There is this big highschool where everyone meet their partner (there are no love triangles, no broken hearts, the only weirdo without a girls is a guy with glasses that helps a friend a little less weird than him to get the girl) but not much time to know really well these couples.
If the anime showed us the half of the couples giving us the time to build a connection with them, maybe it would have work. But for God's sake there are like ten different couples in 12 episodes of ten minutes each, two hours in total.
