I Tamed a Tyrant and Ran Away
This manhwa is the one I have read in novel from the very start. I love this! The strong character of the FL and the kind strong ML. At first it was kinda scary that the ML might appear the obsessive type(well FL said its okay to have a purpose on his life that made him fall love on our FL freely never suffocating)but as you read it. He proves how great his respect to her. He doesn't force her or own her even though he is now the emperor. He shows how he adores her step by step. He help her on revenge even without knowing why?, He surprised her on her birthday that never once her family speak of, he drew her a portrait, give the best room in the palace, he always listen to her, he even massages her feet, He plays the piano and sings to her etc.. Speaking for 6 yrs. He kept it. The ML is the purest if you really observe thoroughly that's why he wasn't affected by the demonic call of the sword in their past life. The FL personality is understandable. She is also nice to him but it seems she just using him. Fl grew without love of her family. She became an evil sword for 400 yrs. Imagine that. Your emotions will definitely shattered. It's good that she is still sane. The ML at last reached the FL's heart Let my characters be happy! Having a sincereful love in times of revenge.
