Misunderstanding

Honestly, on one hand, Ji Hwan felt sorry because he realized that Lionel's decision to do something like that must have sacrificed all of his feelings! But on the other hand, Ji Hwan was grateful because Aura and Lionel didn't live in a forced marriage.

Although Ji Hwan cared for Aura and Lionel as friends, but he realized that love could not be forced.

Although Ji Hwan approved of Aura and Lionel's marriage, but he knew it might hurt the two people he loved.

Although Ji Hwan often felt annoyed with Axel, but he realized that Axel was the one whom Aura loved wholeheartedly. And most importantly, Axel loves Aura!

No matter how hard Lionel tries, Ji Hwan realizes that Aura won't be able to turn away from Axel. So, approving the relationship between Axel and Aura is indeed the best option. At least, only Lionel will be hurt, not all three of them. It might sound cruel, but what else can be done? Love can be cruel, right?

Perhaps he seems indecisive, wasn't Ji Hwan
