I can’t remember the name of a series I’d like to rewatch.
In America, a man (A) is either murdered or an unsuccessful attempt is made on his life by his greedy relative (illegitimate? cousin? half brother?) Before this, A had been writing or drawing a yellow flower on a card.
Back in South Korea, an identical looking man to A is seen by the grandmother who believes him to be her grandson.
The murderer is jealous, he knows/believes this man is not A, but cannot prove it. There’s also a young woman who was a witness to the dead man being alive - she also is in South Korea.
Does anyone recognise this Kdrama?

BTW - I’m almost sure there is money or inheritance or greed or jealousy involved somewhere, hence the murder/attempted murder.

Thank you
