Me, My Son & Keisuke

Kitagawa, a lawyer who lost his wife, temporarily closes his office to raise his young son, Sakutaro, and works as a part-time university lecturer. Feeling the limits of raising a child alone, he meets Keisuke, a student at the university where he lectures, and hires him as a babysitter. Kitagawa finds himself increasingly drawn to Keisuke, who brightens up the atmosphere with his unique cheerfulness and diligently takes care of Sakutaro. (Source: Gentosha Comics, translated)
