Seria really loved him and he did too, but he felt responsible for Lina, always spending time with her and doing whatever she wants, she asked him to go to the glacier with her ( a place Seria goes to to make sure there are no monsters) and although he promised Seria not to hang out with Lina anymore he went with her a few days before their wedding, when it comes to a stern if the husband doesn't show up on time for the wedding she dies and he knew yet he went with Lina and got stuck on a storm, so Seria was left alone on her wedding day

Oh no, it would be tragic if she died but no, the og Male lead who was supposed to love Lina saved her by marrying her instead, and kalis who was in the glacier with Lina was forced to marry Lina in order for him to survive, and he had the audacity to blame Seria for marrying another guy lol anyways here's the link :

They made the sub male lead such a looker but he can rot in hell for all I care.
