My Youth Romantic Comedy Is Wrong, as I Expected @ Comic, Vol. 20 (Manga)

But as the festivities wind down, Yui has a very personal request for Hachiman...one that has him thinking seriously about her. With the real Soubu High School prom on the horizon, what better setting is there for some classic teen drama?
