after training a lot today, your exhausted self left the training room and returned to the dorms. you entered the common room. the lights were out and no one was there... which was weird for the common room... suddenly the lights turned on and your friends all jumped out of some hiding places with gifts and other stuff, yelling happy birthday. you jumped up in surprise. you had forgotten all about your birthday... you whole class was there. even bakugou, and little eri, who was holding a plushie for you. (Mr. Aizawa probably gave her money for it) sato walked in with an enormous cake "have some cake!"
