Live-action series for this one and Mood Indigo (prequel/sequel) are available for free on Viki Rakuten.
Oh wow, I’m loving the choice of actors. The look and sound amazing ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄

Tits odaema is neither romantic nor sexy.

Eunho sleeps (forever) with a stake in his heart and his coffin nailed shut. 1 down, 2 to go - love, Junwo.
I am looking for a similar Webtoon where the protagonist is the background character.
He watches the other people's romance, and we never even see his face until the very last panel. It's also based in school but they have green blazers I think.
It's Full Colour shounen ai.
