The harem reacting to Takemichi pouting or saddened
Mikey would nuzzle close to Takemichi and try to make him happy so no one else would see it. A pouting Takemichi is a sight for him and only him.
Draken's heart would be beating so fast to the point he believes he's about to suffer from a heart attack, but he still squish his cheeks.
Chifuyu and Hakkai takes lots of pictures so they could put them as their background later and gives lots of hugs and cuddles to make him feel better.
Baji would be aggressively flustered and would be trying to bite his cheeks without hurting him, because that would make him sadder.
Inupi would cuddle with him and let Takemichi nuzzle his face in the crook of his neck, till he's satisfied and ecstatic. Anything to make his cute boss happy.
Kokonoi would buy anything Takemichi would want, even when Takemichi tells him there's no need for it. He still does.
Kazutora would playfully biting his mochi-like cheeks, which would make Takemichi giggle.
I couldn't write something for Mitsuya, Sanzu and the four heavenly Kings of Tenjiku😔 but I will try later for them.
