You and Iida have been friends since childhood. You and him are always together. You will go through the joys, hardships and sorrows together. Iida likes you but he never confesses. Until one day you told him that you liked Izuku. Instantly Iida's heart felt like it was breaking into pieces. Iida felt heartbroken but he pretended to be happy supporting you.
He helped you to get Izuku even though in his heart he hoped you would turn around and choose him. But that never happened. His love was never reciprocated.
One day when the bell rang, Iida was walking down the hall and saw you in the distance holding hands with Izuku. Iida couldn't help but smile. He is happy to see you happy even though he is the one who has to suffer. It didn't feel like he was shedding tears
