Same. Theia fucked her step-sis. What did she think she'd achieve through 'em. And they call their affair a "fling". Girl, have a little bit of sense would ya.
It's incredible. (⊙…⊙ )(⊙…⊙ ) And Sheryl got hurt because her sis/ love interest called their relationship pure sex. Clear Sheryl wasn't ready for that. Oo
So that's the connection between Sheryl and Theia.
Can't say I don't feel a little bad for Sheryl now.
