Fanon
Yukimomo is amongst the most popular ships in the IDOLiSH7 fandom due to their consistent interactions, the history in between the two characters and "married couple act". It also grew in popularity after season 2 aired in April 2020, as more fans were made aware of them and their dynamic.

Some fans also ship the characters they play in an in-universe story, such as Karasutengu (Yuki) and Uta (Momo) from Ayakashi Mangekyo Karatogaokuri.
