I'm looking for a shounen-ai or nonexplicit yaoi manga where one of the main characters is completely selfless.

By "selfless" I mean attitude like "I don't want to bother others with my existence" or "I don't care about what happens to me". Or anything that results in the other guy caring about the said character more than the said character cares about himself. I hope it doesn't sound complicated.
It would be nice if the selflessness (that's a weird word) was a result of a trauma or something like that.

What I mean by "nonexplicit yaoi": I avoid yaoi with frequent detailed sex scenes. The sex can be there, but just hinted or shown without details.

Some examples of manga like this that I read and liked:
Hanamai Koeda de Aimashou
Koori no Mamono no Monogatari
Ake Nure Goyou ni Furu Yuki wa - had some explicit moments but the character from the main story is very much like what I have in mind.

I have a weakness for this type of character 🙂

To me, these would fit, though none are as obvious about it as Koori no Mamono no Monogatari.

Nanao in Mujihi na Otoko and Mujihi na Anata - you might think they're too explicit though.
Naoya in Love Mode
Konbini-Kun

I know there are more... just have to remember them.

Aegis

Uragiri wa Boku no Namae o Shitteiru labeled as shoujo but there's some heavy slash going on

Count Cain

Oriolidae & Sparviero

OMG YESH! I totally agree with the recommendation Mujihi na Otoko. Nanao is such a lovable character~ and I just adore him. Anyways, why not try Hana No Mizo Shiru?
it's shounen-ai

-woops last time i check it said shounen-ai xD-

It's not BL, but alludes to it. It's really a close relationship between 2 people who happen to be both guys.
