I Cannot Reach You manga volume 3 features story and art by Mika.

It’s eating him alive. His jealousy, his possessiveness, his yearning to be more than “just friends”…But Yamato is absolutely terrified of losing his best friend Kakeru if he ever admits the truth—that he is and has been in love with him forever. Although hidden from Kakeru for years, when Yamato’s feelings overflow and he awkwardly hugs Kakeru in a jealous fit, will this be the catalyst they need to confess to each other? Or will their desires remain just out of reach?
