Kawaii Koi wa Kikazaranai - Ch. 36 - I Was Confessed to by the Person I Like, but Now I Can’t Contact Them

[LTalon]

Not to mention no social media account to contact her and let her know his phone's busted

He also has several mutual contacts that he sees regularly that could pass a message to her being like "phone broke, gonna be kinda hard to contact for a bit".

But all of this DOES assume he has social skills and the forethought to do that. Which...it's Yuusei, he doesn't. The guy's brain has room for Shogi and cute clothes and basically nothing else.
