What if Taeha is an illegitimate child or something, and maybe that's why he's a bit fcked up in the head. Not to mention his big brother who seems like a big ass and a bully. Taeha has been described as strange or has a disability, perhaps he's really like this weird sociopath who's generally nice to others but basically lacks real personality when it doesn't involve Haesoo.
