I'm guessing something heart-warming happened but the japanese leaves me dumbfounded

Since I just translated words, lemme try translating pictures.

Kamijou buys a ticket, even though Hitomi already has one. Hitomi's like "I already have a ticket" and Kamijou realizes he unconsciously bought one for Sayaka. Hitomi makes the loaded statement and Seiyiku lose it again.

Small but significant correction on one point:

Kyousuke shows up with two tickets and gives one to Hitomi. She notices Kyousuke's name as a guest performer, and asks why he got a second ticket in that case. He realizes he unconsciously bought one for Sayaka, so Hitomi takes that one too, to 'reserve her seat'.

Thank you, very heart-warming...
