10 years ago, being the innocent manga fan like many of us were, I searched for "naruto sasuke backgrounds". Curiosity-driven clicking and an accidental disabling of the google adult filter led me to a manga website where I almost naturally opened some manga with a cover of two guys. Little did I know that this was the magnificence that is yaoi. Little did I know that this moment would be the monumental conception of my sexual and romantic curiosity.

10 years later, I'm extremely reassured with my sexuality, have been through multiple relationships, and am an active LGBTQ+ advocate in my community, but I still feel empty and restless today, unable properly thank and appreciate the manga that made all this happen.
I implore all of you for your help.

This is what I remember of it:
- the two guys were childhood friends
- one guy cuts his finger with a knife, and the other person licks it
- one guy gets hospitalised, gets put on the stretcher, and the other guy licks his nipple out of curiosity, but runs away out of embarrassment
- it's an original story
- the manga is complete
- the style is more modern, rather than the old Japanese sharp-chin style
- this was made from 9 years ago to ~13 years ago

I greatly appreciate any sort of help!
