English title: The Salted Fish Has Gotten Over It/ Moved On
I really enjoyed it! I usually get bored by sweet, fluffy novels but I was able to enjoy this until the end. (Although the last twenty or so chapters did drag a bit). The MC was really spoiled and pampered but it wasn't overly saccharine because the ML had such dark, possessive thoughts that he was suppressing to live up to the MC's idea of him as a good person so it worked really well!
Summary: MC had a heart disease in this original life and after her gets surgery he's reborn as the brother of the protagonist in the novel he was reading beforehand. In the novel, the protagonist is reborn and gets everyone to love him. The brother was supposed to commit suicide after the protagonist stole his fiance but the MC changes the story. The prince the brother was married off to was supposed to die a few days after the brother commits suicide so the MC thinks if he waits it out he'll be a salted fish widower. The prince/ML doesn't die and instead he gets pampered by the prince the whole time.
Really cute, love how both of them pretend to be ill to get what they want. MC is kind and dumb but not easy to take advantage of. Like how ML is pretty unforgiving to others.
