Wanting to know shounen ai manga title PLZ heLP!

Ok so I was in a comic store and they had a small manga section. I didn't have the money to buy it, but I had a shounen ai manga in my hands and flipped through it quickly. I forgot the name so maybe someone can help out-!

-I swear blue or something was in the title(no not blue sky complex)
-The cover was super blue!
-One blackhaired guy and he was a little chubby; he was gay
-The other dude was popular in school kindof; typical handsome guy
-High school setting
-summary went a little like the blackhair guy is gay and the other became interested/curious
-Their height difference wasn't that big
-The artstyle was pretty soft
(obviously it is licensed in english)

The art looked super cute and I regret that my phone died/I forgot to write down name nooo- I can't find it anywhere so if anyone can help me out it would be amazing ><

(I know it sounds a little generic but??)
