OMG I replayed the game recently...and sth caught my eye
When MC first met Luna (in 2019), she used the excuse "left the oven"....
And when Luna first met MC (in 1999), he used the excuse "left the oven"...
Did Luna know the guy she first met in 1999 and the boy that her daughter likes in 2019 is the same person (AND possibly Skyar's father!?!?!)
So that she urged Skyar not to contact/take the relationship further with the MC...
and the "left the oven" is the hint that Luna wants to give to the MC in the present timeline, as this is the excuse that was used in 1999 by the MC.
or I might be overthinking....
If someone said sth similar before, i have to say sry but i simply can't go through 100+page to check if some theories has been called out or not. XD
Edit: I few clicks later i realized the MC has a similar revelation as well.. XD NVM me
