After Getting Together with the Senior I Admired, He Said I Was Just Playing Around

I pursued my senior with such joy that I thought I would marry him after graduation. But I heard the senior lazily saying to his roommate: "Is she worthy of marrying me? I'm just playing." Later I interacted with male guests on variety shows. With a gloomy face and red eyes, he blocked me in the corner: "I haven't broken up with you yet!" Who said you were just playing with me in the first place?
