Is it possible that maybe Cain remembers their past lives wherein jooin is yahwi's lover but then cain love jooin in the past but it's an unrequited love and that is why he is trying to steal jooin from yahwi in the present time.
Umm can I share my think? I think it's about childhood memories? Like you know there's spoilers about Jooin met Yahwi back when they was a kid. Maybe it's the same case with Cain, they met at a place somewhere when they was kids. Well Waje-nim love to make a fated couple with childhood memories with them
