Eunseok was the principal's son soo he was popular too he was kind he was always surrounded with the students. You would consider yourself lucky that you were always in the same class as eunseok lol was it a coincidence? it probably was for you... but you didn't know he was your stalker....he did everything to be around you , managed to be always in the class as you for years , even applied at the same university as you with the same major you applied for....he was pathetic..no one knew
