Ma-kun is an idiot

OMG, babe! I just discovered that my super sweet friend, Ma-kun, is totally being a big meanie and cheating on his precious girlfriend, Na-chan! Like, seriously, I can't even! I'm just heartbroken and super duper disappointed, 'cause I never thought he could be so hurtful! It's like, what a crazy twist! He cried rivers when he got cheated on, and now he's hurting such a lovely girl?! Ugh, that’s just sooo unfair!

A part of me wants to tell Na-chan the truth...but I'm afraid of losing my best friend
