it's my opinion, but i genuinely believe NAmwoo doesn't deserve Sieon. as far as I see it Namwoo continued to date Sieon seeing what type of person he was, if he was dissatisfied with him,he should have left from the get go, he knew sieon had no problems telling people about his relationship, but sieon lied for him, namwoo doesn't know the conversations him and his sister were having but he's quick to judge and lash out at Sieon who has been living for him from the moment they started dating. sieon introduces namwoo as his bf. while namwoo kept saying they don't have a label.
