I hope the grandmother did a last "Fuck U" to her son. As in, knowing how petty & scum he is, paid the lawyers to not change her new will, and pretended to her son.
This!! I keep seeing yuri or mikhail or alexei but this is really the only one that came to my mind if there's no plot twist stating that Alexei and the FL are not siblings
But damn if Garen wasn't in love with his wife, I would totally be ok with him and FL being a thing.
From wanting to slit each other's throats to
romance and the age gap, letting a man syill look handsome even with wrinkles
Ahhhhhhhhhhhh a girl can dream ╮( ̄▽ ̄)╭
