So, the type of BL manga I like are serious and dramatic but with an air of sweetness, and are usually slow build romances. I've started resorting to rereading the ones I love so I'm seriously looking for more suggestions. I don't really like anything too goofy or lustful "I'm going to jump you immediately" type stories. Here's some examples of my favorites that have the atmosphere I'm looking for:

Seven Days
Given
Hidamari ga Kikoeru
Hana no Mizo Shiru
Hana wa Saku ka
Kikoeru?

I also love Yuuutsu na Asa, it fits this theme a bit but is much more serious with darker themes

Me o Tojite 3-Byou

Might be something for you. 🙂

uhhmm, have you tried any of the manga of YAMAMOTO Kotetsuko ??
