Seo yul bacame furious immediately when he heard what she just told him telling her how he sucked the blood of the woman he gave his heart to without him realizing it and that is the instinct of a vampire asking her if she really wants to live that way and also saying has she been trying to seduced him all along just for him to turn her into a vampire,she was tongue tied and couldn't say anything she was just listening like a baby been reprimanded.
He told her his heart was still human but his body still constantly need human blood atleast once a month to survive ask her does she knows the number of people he has killed just for him to keep his life ?
Still furious he took out the wooden stake which he usually carried with him walking towards the vampire he just apprehended few minutes ago.
As soon as he raised the wooden stake to stab the vampire in his heart she shouted out trying to stop him while also reminding him that the moonlight was still up and yet to go but he ignored her and went ahead to stab the vampire.
Immediately he stabbed the vampire, the moonlight disappeared and the vampire died but by doing so Gwi was also able to sense his presence and he immediately stood up from his cave where he reside .
Gwi immediately jumped onto a roof saying to himself that seo yul is a good hider same as his teacher the guidan vampire who turned seo yul to a vampire saying he hid well like a mouse.
While thinking of what seo yul might have been doing for the past 120 years he eventually found seo yul who was also ontop of a roof looking at him.
As soon as seo yul met with gwi once again he immediately turned around and was about to leave but gwi stopped him by asking him if he thinks by killing homeless vampire all year long does he thinks that it can resolve the sorrow of his lover who sacrificed her life just to save him.
By saying this he opened up the deep scar which was etched in seo yul a memories and has caused him endless torment.
Hearing this seo yul also recollected what happened that night 120 years ago and immediately tears were threatening to fall out from his eyes.
He immediately started to run while still on air but gwi chased after him . Seo yul then stopped in his track saying to gwi he knew it was disgusting but he will endure it.
Gwi taunted him to come after him but seo yul just replied him saying he'll endure it for now but he'll make sure he is the one that will be the end of gwi infernal life, then he turned around and left.
