I Thot You Was a Toad's manga / #single dad(2)

Tsudere, single father is overly attached to son and pitches fits at any thought that someone will romance him away, even mistaking the true direction of a suitor's affections, which leads to schemes and plot complications.

Domestic couple story. Hajiwara, a single gay man who had been rejected as a child by his father and stepmother after the remarriage, vows he will never put another child through this experience and swears off all family men, no matter how attractive he finds them. Fortunately, he is no match for Yuuto Maki and his very cute son, Ritsu. There are moments in the story that give pause, but the overwhelming feel of the manga is cutesy wootsy.
