If they beat Gi Seok I think there will be a second round with the ex love that is Eun Woo's mother.
Honestly I would love to see her rather than gi seok in this one. although usually I hate when they bring ex back when the relationship just started, I think she would make a great addition. if she comes I think it will be more to ask for the kid back rather than the male lead
I would say on the way to the airport felt similar
Yeah I'm obsessed with this drama :P. Its similar as in both main characters are married or in a relationship and they develop feelings for each other. On the way to the airport has a sadder vibe. You should give it a try I really liked it
