It could be Yellow... http://www.mangago.me/read-manga/yellow/
I think it's Steal Moon. Lemme double check. Yep it's Steal Moon. http://www.mangago.me/read-manga/steal_moon/an/steal-moon-chapter-8.html/2/
It's an artwork from Yellow http://www.mangago.me/read-manga/prince_sapphire/tr/102868/page/25/
(written in the corner of left side)
Anyway, it's the same author so all the characters look similar to each other ^^
Hey guys! :) do you maybe know the second manga on the left side? (guy with the cross) I'm looking for it for ages ╥﹏╥ thx :)
