Summary
The Person I Met In-Game Was Actually My Big Sister. (Colored)
"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!
