i think it’s apart of his unstable character, i don’t think he’ll actually do anything crazy or evil to won-woo. i feel like this story will be about won-woo teaching and coaching taeshin into loving properly. taeshin’s whole problem is him loving someone expecting to hate them instead of loving someone expecting to love them; i think won-woo will help him heal and understand not to be so afraid of love.

i dont think he’ll be a red flag but he is having those kinda like “yellow flag” moments were he has those crazy eyes and he mentions how he wants to “ruin” won-woo so im wondering if that’s just part of his like slightly emotionally unstable character or is it foreshadowing…??
