I get it that everyone want Itsuki to be happy. But dont you feel anything when Airi have a feeling for his own brother BUT STILL HAVE PERFECT CLEAN CUT OF ITSUKI'S SMILE IN HIS MIND?
What i think is, Airi is in love with his brother but he tried to move on or break the feeling and always remember Itsuki's smile. He want his smile but the progress of his move on probly took long enough ╮( ̄▽ ̄)╭










You know the shit when its Harada-sensei. The real God of torture (=・ω・=)
