First of all the reason why he can't say anything or talk things out because they don't have label and he's afraid of getting rejected. Do you think it's easy to confess to your crush? I bet yall can't even utter a word. And besides he is unsure wether ML truly likes him what if he doesn't? They don't have a LABEL or confess to each other yet. Let's say ACTION SPEAKS LOUDER THAN WORDS but y'all don't understand it's hard to conclude anything if you aren't sure wether the other party likes you or not.
I love how the story is constructed. The story is quite wholesome though it has some smut scenes but It never break out to it's storyline.
