Tohsaka Rin by Yousei Cosplay

Shirou: Just because we're on the same side, don't try to get chummy with Tohsaka.
Lancer: *doesn't get it*gets it*lols* Oh, I see! Good for you missy!
Rin: Wh-What are you babbling about? We're just allies, nothing more! Go on, tell him Shirou!
Shirou: ...
Rin: S-Say something, you jerk! I-It's as good as saying that we really are a couple...
Lancer: "Really are," nothing. You two have been an item for ages.
