Painful Love (아픈 사랑, Apeun Sarang) is chapter 48 of the Twelve Nights webtoon.
At night, Dan Ah ponders about the recent happenings, especially about Won's real identity. Nabi arrives and listens to Dan Ah's thoughts. Dan Ah tells Nabi that she would not, after all, change her feelings for him even if he was not the one who sang the lullaby. She thanks Nabi for her presence, all while he represses his feelings.
With some time alone, Hwi blames himself for all the failures and sufferings he had been causing, such as the failed assassination on the king. He pleads for help, especially towards Jeok.
