I'm sure Minhwan caused that accident - and I'm even more sure that Jihwan was the one who warned Ganguk by writing…
Exactly! It's as if Ji-hwan remained by her side as a guardian to protect her and he found an ally in Gang-uk also because let's not forget that they "share" the same heart!
I think Min-hwan has something to do with his brother's death. Ji-hwan even as a ghost continues to love and protect Yeo-ri and he proved it by kicking Gi-u out and calling off their engagement, something he didn't do with Gang-uk because he saw what a sweet, funny and beautiful person he is. I'm loving this series more and more!!! 😍
