Bare my skin, bare my soul (слэш)

In an alternate universe where everyone's skin is decorated with the lies of their soulmate - or liemarks - Tony Stark is fed up. His soulmate lies constantly, and not just about normal things, about things like murder, treason, and espionage. He talks like he lives in a different century and has instilled Tony with a million and one frustrated questions.
When an astrological anomaly is picked up by SHIELD in Puente Antiguo right as his soulmate seems to be losing the plot properly, Tony decides to investigate and finally get the answers to some lifelong questions from his soulmate.
Question 1: Can they just give up and come out already?
Or, a soulmate AU where instead of soulmarks, people have liemarks, set during the events of the first Thor movie.
