So their relationship just fell apart, just like that. Looks like Tsubasa did fell for Chihiro since he was thinking of her. Lust to love eh? Haruka deserves a more decent guy. I wonder what was the purpose of having a character development for Tsubasa If he will just cheat on Haruka.
But what the Hino guy said made sense. Haruka is an independent girl. We all know she really likes Tsubasa, but I guess she didn't fell deep enough to be a total damsel in distress. Good Job Haruka!
