Am replaying Halloween otome to take a break from getting every line in Valentines otome (I'm goddamn getting there though) and I HADN'T REMEMBERED this line! I know I'm probably overthinking it, but hear me out. In Eric's route, on their second "date" as they're talking about the famous bakery, he says "Halloween isn't the only day they have special treats for. They have ones for Valentines, Christmas and even White Day."
Now. He said that in the exact order the games have come out, except white day. Coincidence? Probably. But I just want a fourth game so bad, Imma huff whatever copium I want.
