I just think he hasn't accepted his feelings and the fact he likes men yet. When he saw ohlala looking, he felt like ohlala was able to tell what he was thinking and was judging him for being a homosexual. So he got overwhelmed/scared and left. It's annoying, yes, but understandable. THEY'LL GET THEIR HAPPY ENDING!!!
I CAN'T BELIEVE IT'S OVER ALREADYYYY I've loved it! Lil bit confusing nearing the en, probably because I kept forgetting the plot between chapter updates But genuinely, gorgeous art and I would definitely recommend it. I just REALLYYY wish there was more focus on the romance between the main couple (like AFTER they actually confess their feelings for each other), as well as Seina and Ellen's relationship bc that last chapter was too much of a truth bomb. I HOPE HOPE HOPE there's side stories or extra chapters
