I think it makes sense that sari ends up with no one, as she is afraid to start a relationship again. if she ends up with harim he's too young, if shewas with his boss maybe a little uncomfortable because of the scandal, if with an old friend she just didn't want to ruin their years of friendship.in the end she did come back alone
i love this drama, make me cry when they finally getting together. it's feels like I'm with their when in highschool to university and finally getting married 😭
