\"Big Sis!?\"
\"Kouta!?\"
The two of them were enjoying an in-game romance (without knowing each other\'s identities). Upon seeing each other\'s faces at their long-awaited offline meetup... they were both shocked to see that their partner was in fact their own sibling!?
These are complicated feelings for sure... and rather hard to accept!
