Lines 300 to 304 (new) suggest he knows even if Eric say "You are just imagining shit"
If the rest of Sai’s dialogues are supposed to stay unchanged, maybe something should be added here to emphasize that Eric is trying to convince him that no, they’re not dating… At least, that’s how it seems to me…
EDIT: OR just remove this lines that aren't so important after all...
sa"I saw you two talking...she seems to like you..."
e"Wha...what!?"
e"You are just imagining shit"
play sound "malesmirk.mp3"
sa"Maybe...maybe not..."
But also perhaps I misinterpret this!
