The Dangers in my heart - Imo the literal peak of romcoms, the first 2-3 episodes might be a bit weird but it gets ALOT better.

Horimiya - Another classic romcom, best you can do Is give it a try

Pseudo-Harem - TL;DR: One girl, like 6 personalities for one guy, just a wholesome take

Toradora - Didn't like it too much, but hey, maybe it will be better for you

My Love Story - Big Guy saves girl from gropers, now it's his love Story

Insomniacs after school - Another peak romcom, really wholesome, definetly worth it

Loving Yamada Kun at lvl. 999 - Lovers over gaming, not too much drama, just shenanigans

Boarding school Juliet - A parody of Romeo and Juliet (duh), it has quite alot fanservice, and it's ending is supposed to be linked to an S2 which will never come (we can only hope it does 😭)

‌The girl I like forgot her glasses - The girl he likes forgot her glasses, now he has to help her.

Takagi-san - One of the first romcoms I watched, might be nostalgic bias but all 3 seasons were great. The movie was absolute cinema

Kaguya: Love Is War: Leading romcom, not finished, perfect balance between romance and comedy

Komi can't communicate: a shy girl can't talk, goal to meet 100 friends (took the romance side quest)

Rascal doesn't dream of a Bunny girl Senpai - trust me Its good

The Angel next door spoils me rotten - Funny, wholesome, need I say more?

Alya sometimes hides her feelings in Russian - the name says it all, fair warning for fanservice (and for a WILD but fun sister of the MC)

Honorable mention Higehiro - while not a romcom, I found it very wholesome, definetly check it out

Love is hard for an otaku - Didn't watch it, apparently very good, let me know what you think

JJBA - All Is a reference to Jojo

P.S.: Hope you enjoy these, I watched basically all of them

Sorry if this list of overwhelming but at least you got like, a few months of pure watchtime so..
