While it HAS been shown that we'll have mystical/mythical god mumbo jumbo stuff with the reincarnation plot and ms. red IS the one who brought/reincarnated MC to this world, I have to agree with everyone that the god plotlines were definitely not needed. Heck, a literal antagonist wasn't needed. For me, I could've survived on the formula/story we currently have, a misunderstanding between 2 people in their fraudulent marriage.
Guh... why couldn't we just focus on the first half? Like Del getting hot and bothered like that made ME feel the same way! TAKE HIS G*DD*MN CLOTHES OFF RINRIN AND PROCEED TO WHAT SHOULD COME NATURALLY AFTER GETTING MARRIED!
