So it's set in modern world. FL is living in an abusive household where she is hated and treated as a servant. Evil second female lead agrees to give her money for sick mother's medical treatment if she spends the first night with ML in her place because they look similar. ML is hot and rich, but somehow has a problem rembering girl's face and thus is successuly decieved by the second FL wearing the same dress and urging him to "take the responsibility". Afterwards ML comes to meet the family and FL is still has to serve all of them but forced to wear a mask. Later on ML realizes that there is a scar (or a mole?) on one of the female leads shoulders but not the other. And then poor FL is held by abusive freaks and actually burned with a hot metal to cover it up.
It was really into watching this drama on YT but it was deleted before I've finished it. And I've tried searching it on the website using diffirent tag combinations but to no avail.
