Birth Secret (2013)

I'm not saying that this is the same, I just thinks that if you take the insane people in this , well you can find their counterpart in don't hesitate, and it also carries that unconditional love kinda of scent.
Don't hesitate is about Soo Hyun a girl who makes the ultimate sacrifice for her first love, Min Young by donating her kidney to save his life. Then she gets betrayed. Her best friend, Sun Ah, seduces and steals Min Young away from her. Devastated by the betrayal, she meets Tae Woo,who is determined to not let anyone close to his heart.

Again if you just take it as a all then they don't have much in common if just the amnesia part. Ji Hyung is engaged to a woman chosen by his family, but he loves Seo Yeon, who he has been dating for years with the understanding that their relationship would last only until Ji Hyung’s marriage. The wedding date is set, the two break up, heartbroken Seo Yeon starts to forget things, first just the small one but its soon escalate to more important things that alarm her. As Seo Yeon’s memory loss becomes more severe, she learn an life shattering true and Ji Hyung must choose.
