My loli senpai is my mom.

Synopsis

With both his parents dead and his stepfather also having died suddenly in an accident, he had thought he was utterly alone in the world—until he suddenly received a call from his stepmother, whom he had “never met,” clamoring to come to his university dorm to deliver a freshly dried comforter. Arriving at the school gate with mixed feelings, he found that waiting for him was no middle-aged woman, but a petite girl with twin tails, just over five feet tall, struggling to carry a huge comforter—clearly his sophomore loli senpai! He couldn’t help but cry out inwardly: “My loli senpai is my mom?!”
