Right before midterms. While studying together in the clubroom, they discuss grades and learn that Tomoyo has the worst grades in the group. On their way home, Hatoko asks Tomoyo if she'd like to study together. Together they study and talk about Andou when Hatoko accidentally lets "that's not fair" slip and unsettles Tomoyo.
Hey, Chi-chan, when do you 
usually feel your chest hurt?
أخبريني يا تشي-تشان، متى ينتابكِ الألم؟
Oye, Chi-chan, ¿cuándo 
comienza a dolerte el pecho?
Dis-moi, quand est-ce
que tu as mal ?
Ehi, Chi-chan, di solito quando ti fa male il petto?
Ei, Chi, em que momento 
seu peito costuma doer?
