Abe-kun's Got me Now! Vol. 6 (Kodansha, 2021)

With Abe's karate tournament safely a thing of the past, the scene shifts to December, which can only mean one thing...Akari and Abe's very first Christmas!? Abe wants to know what Akari's favorite thing is, so she proposes a game: if he can figure out what that is, she'll give him anything he wants. Surprising absolutely no one, the gorilla boy is all too happy to rise to the occasion!
