i am squid's Manga

Btw, the male lead is not shitty. He is under the influence of the author and hence forced to hate fl without being able to form a concious thought. Fl fulfills the conditions and break him free from the author's influence. He started to accept his feeling for Fl and even starts to defend her, even suspecting the Og Fl and his brother

In a nutshell: (I absolutely adore this manhwa)

Loved ones betrayed you? Go back to the past after you get poisoned. Get your self a poisonous husband who kill you twice, accidentally and intentionally. Find out that your in-laws blood was the reason you and your dad died in the past. Love them anyways because they didn't mean it. Your rival is a crazy princess who drugged your hubby once. Now see how things go.

Very respectable male lead and female lead who needs saving from her horribly twisted psychopathic elder brother.

Seriously better than I expected. Totally in love rn.

Honestly, this is the best bl I've read so far. It's not "toxic" and the application of psychology, the feelings and everything is so good. The character and their anxiety gives me chills. Hope Inwoo gets better soon
