Siwoon is your boyfriend. You know you're not his priority. You know it's dangerous to date him. But you also know he loves you. He loves you sincerely. He's strong and will protect you with all his might. He cares for you. He loves you and he protects you, but not from his master.

He's strict and serious when it's necessary and he won't hesitate to really punish you if you do something really wrong. He may be strict with you sometimes, but only if necessary. Afar from that, Siwoon is very gentle and caring with you, only with you. He could be possessive and consider that he should know everything about you, but he is still caring and gentle with you in private and he never raises his voice at you. But even with that, you both still not share much physical contacts.. It's something so new and strange to people who were raised to be killing machines from the childhood like you two.. Not much physical contact, but enough mental support.
