Amante o extraño (2021)

Both dramas are about an amnesia story where the female lead finds out she is married/the fiancé of a guy. Said guy tries to be understanding and helpful of the girl, however something seems suspicious about him. Both have very well done story twists that one does not truly see coming.

They both have girls with amnesia get place surgery and look like the his girlfriend they guy tries to find where his girl is some differences are that Nakark Kaew has him mad at her because she cheated on him but that does not happen in Lover or stranger.

In both dramas the couple is already married from the beginning of the drama and they used to love each other , but the male lead is a questionable character with many hidden secrets.
Both dramas are romance/thrillers with suspense
In both dramas it is implied that the male lead (husband) keeps the female lead (his wife) locked in the house (with the excuse of protecting her due to her health issues).
Those 2 dramas are very similar. In both dramas the male lead loves his wife deep inside, but he has a possessive attitude and is obsessed with control. Those are signs of abuse and therefore it's wrong to exist in a relationship.

Ou Hou is the ML in the Eight, a republican drama about a fresh graduate who finds himself entangled in the affairs of a guild that represents eight professions (spies, sages, mechanics, deceivers, thieves, assassins, poisoners and entertainers). This drama showed off Ou Hou's versatility. If you liked him in Lover or Stranger, give the Eight a go!
