why would he need to fight for someone who's not loyal? Plus, the girl is the one that asked to marry him, he's not the one that proposed. So for her to ditched him after that clearly shows that she's not worthy & not trustworthy to be his wife
What He Did To The Elf Girl Is Different In The First. He Can't Have Her Cause She Is Going To Be A Guardian Of Her Village. He Want To Stay With Her But Elf Herself Refuse That Cause He's A Human He Have A Role To Show Maer The World, And The Swore That He Had For Maer's Parents.. So What Can He Do.. He Only Ends Up Heartbroken That He Can't Refuse Her And Leave Quickly Cause Of The Pain..
Dude is a coward, both girls wanted him but he never really talk to them and ask them their feelings about him. His fiancee look like she's being forced to accept the hero but he didn't fight for her at all n just ran away then fall in love again and did the same thing. I hope the sister is okay, that peddler merchant dude look shady
