A new season titled Ossan's Love Returns aired on January 5, 2024, with Tanaka, Yoshida, and Hayashi reprising their roles.

Unsettled by Kurosawa's bold confession and romantic pursuits, Haruta seeks advice from his friends, discovering in the process that his male co-worker is also in love with him.

Ossan's Love was inspired by producer Sari Kijima's [ja] experience of being looked after by a female friend while in college, and her desire to explore the subject of romantic relationships between co-workers.

[1] Scriptwriter Koji Tokuo [ja] noted that rather than writing the series as a moe love affair between men, he instead framed it as a romantic drama that merely features men instead of a male-female couple; consequently, Ossan's Love specifically avoids depictions of homophobia or other LGBT-related issues.

[2] While Ossan's Love is an original work, Tokuo has noted both shōnen and shōjo manga as among its influences, particularly Marmalade Boy.

[5] The program starred Kei Tanaka as Soichi Haruta, Kōtarō Yoshida as Musashi Kurosawa, Motoki Ochiai as Yukiya Hasegawa, and Sae Miyazawa as Asuka Minato.

[12] The series was collected into four tankōbon volumes published by Kodansha: A Cantonese-language remake of the first season produced in Hong Kong was first announced in February 2021.

[19] The series' popularity is noted as influencing the production of live-action television dramas and films featuring male-male romance, such as Pornographer [ja] (2018) on Fuji TV, What Did You Eat Yesterday?
