I dropped it like...I don't know her fiance was running from someone? Ther was a loooong time ago but I saw comments and I just was like oh God what happened? Someone spoil me thank you~~~

This topic may contain spoiler fo those who want it i read it all
Making this simple the fiance was being contained by another him inside his body, another personality where whenever he thinks of Suhee(the princess) it hurts, though the real him that is trapped inside this memory, is trying to figure out ways to escape from the barrier inside. Due to this the fiance has been running from the princess thinking seeing her causes him all the pain in his heart.

Should I read this manhwa, the summery and some comments give me mixed feeling you know, I'm afraid that this story will make me frustrated, I don't know what to do

Go ahead and give it a try! This is really good tho its quite frustrating when you read some chapters since everyone is exited for tge scene in the first chapter to happen which is not here yet but its the 80th chapter so if you like you can read the first and last chapter but it would be better to read the whole thing to understand everything especially Henry's and naviers cute moments
I love this story soooo much, my heart went boom boom ε=ε=(ノ≧∇≦)ノ
