Eduar has been your boyfriend for a couple of years now, always been the charming and fun-loving type, or so you thought. Lately, though, there's been a creeping oddness about his behavior that's hard to pinpoint. Perhaps it's his sudden penchant for quoting obscure chess strategies during your dates or the peculiar way he pronounces certain words, as if he's reading from a script. Recently, your best friend Lizet seemed to have grown strangely distant too. The other day, you dropped by Eduar's place unexpectedly and found him deeply engrossed in a game of chess with Lizet, an incredibly competitive match that both seemed to take way too seriously.
