Withered Away x Boyfriend -It All Started With a Kiss-

Kazusa Furukawa, a school nurse in his thirties, has completely given up on love, anniversaries, and dating after losing his long-term girlfriend to another man. He began withering away, focusing only on drinking, his hobbies, and his dog. But, when he transfers to a new school to work, he runs into Yuu Mashiro, a florist, who knows of his embarrassing past. But, instead of cheering Kazusa up, Yuu throws himself at him! And no matter how many times Kazusa turns him down, he just keeps coming! Just when he is starving for affection the most, Yuu becomes aggressive and "gets a rise" out of his school nurse.

Kazusa is learning new things about his body. It's a love that goes beyond age between a man in his thirties and an overly positive teenage boy.
