Halp.

he always thought his childhood friend was a rival for his unrequited love but he finds out that wasn't the case? im looking for a BL with this sort of feeling.
two boys one girl
she finds a boyfriend which is what starts it.
story revolves around the guys not the girl at any point
only MC likes the girl
other male friend doesn't do flamboyant flirting or anything .. only confesses.
starts off on the rooftop in high school
has some park in the rain scene


i know its alot but its been bothering me for month and the fluffy faint art is not helping me.
