Original summary

As college entrance exams loom large, Tsutsui’s grades begin to slip. Has he stopped caring about his future, or is something else distracting him?

What happens in the episode

Episode 21 keeps the focus on Real Girl’s central problem: it is easier for the cast to judge each other from a distance than to risk an honest conversation. Tsutsui’s otaku self-protection, Iroha’s reputation, and the reactions of friends and classmates all create pressure around choices that would be simple in a fantasy romance but messy in real school life.

PopRot’s recap is intentionally original while staying anchored to the sourced premise above. The important movement is emotional: a misunderstanding, date, rumor, apology, family issue, or friendship beat tests whether the characters can treat one another as real people instead of roles they already decided on.
