@Scylox I don't wanna unnecessary bring your hopes up, but somewhat deep into the story of
, the MC and FMC start dating, but it isn't on the sweetness level of this one. 😔
I've heard good things of
Do Chokkyuu Kareshi x Kanojo, but couldn't quite get into it because of its 'aggressivenes'.
also has part of its story post confession, but doesn't have those sweet moments this manga has, in my opinion.
Kawaii Kouhai ni Iwasaretai already starts pretty much with them being in a relationship, but is more comedy, I'd say.
Kuno Chiyo the Precog has a lot of cute moments and is post confession, but it's also more focused on FMCs embarrassment towards cute moments, but is still really nice.
Saotome Senshu, Hitakakusu is my second favorite after this one when it comes to cute couple moments. But it's partly a sports manga, so that's up to personal taste.
Tadokoro-san is a favorite of mine as cute Yuri couple.
Gonna stop here, but writing this up actually made me realize I've already read a whole involving cute couples. Sorry, for the length!
