That about wraps up why did Kou kept Yuki in the dark for THREE FUCKING YEARS. Still deserved a bitch slap.
Kinda glad Kou tried on his own if he is straight or homosexual, reason why sex ed should be mandatory since kindergarten, because it would save a LOT of hardships like with Sasaki where she thought it was her destined one but Kou had Yuki in his heart all the time when they dated for three months... heartbroken but gave Kou a good advice, hope she found someone who deserves her.
