This will be my guess... The 1st timeline ML probably under the Duke's order/shackles since the FL half sister basically said that the 1st timeline ML works along with jackass "father" for treason against the king and they finally finished, the Duke allows the ML to do whatever he wants to FL and that's probably why the 1st timeline ML was on verge of tears when he saw the FL leaving and FL didn't know this, she's used to being ignored by him and that's why she can't accept that he actually cares for her to the point that he kept her 1st timeline dress in his room before she regressed. I think he genuinely loves her, he just wants to finish everything he needs before settling down with her in the 1st timeline

Again this is just my guess
