Sensei to Boku to Chitchana Marshmallow (Gentosha Rutile Bunko)

[Machine Translation] Masato, who was not a candidate to be the next head of the old noble family, the Gionzuka family, took the opportunity to run away from home to go to college and start living alone, which he was not accustomed to. Masato, who was not a part of the world, was a bit of an outcast on campus.

They are not really father and son, but as Masato gets to know them, he finds himself becoming more and more attracted to Morizumi.
