I cannot comprehend why they started dating??? Like what the fuck weren't the friends talking shit about Naho with Kana and he started saying "He's average" okay cool average is not bad but just imagine throughout your whole life you've been told you're cute but behind your back you are called average?? And also that blonde friend I assume he is blond he assumes that Naho is "one of the pursuers of Kana" but why didn't Kana tell them directly its his fucking childhood friend???? LIKE WTF or maybe its me who read it very badly cause I can't with this shit
