Both of them have tragic background, which explains their all-consuming loves.
Don't worry, while both their love is smooth sailing (a.k.a no ridiculous misunderstanding or jealousy and no hurting each other) the intriguing conflicts in their surroundings are enjoyable enough.
The ML, he's cinnamon roll. He is so good that sometimes, I feel distressed for him.
The MC and ML are somewhat different from the usual role settings. The ML (gong) is the good housewife with nearly unmatched culinary power. The MC (shou) is the overbearing iron claws that can make ghosts regret their deaths. Together, they are THE power couple.
What makes me laugh is that the MC expect the ML to be a 'dog' in bed, but in fact, the ML is a 'wolf'.
everytime he found clearing, he always got involved in (via unintentional eavesdropping) some untold secret, making people want to kill him and thus ending with him getting fortune from dead foes (that he killed). He already do it 3 times! Hahaha
No worries, the MC and ML are safe, sound and HE. Others though... and those extras.. it's so sadly bittersweet
What is the purpose of The Doors, how the ML is.. ML, and who made The Doors?
Some might think that the MC is Mary Su (and she kinda is) but at least MC is very likeable.
And if you think ML is stupid for settling for MC's 'fake' love, then you also must consider their time period's culture and necessity.
