I think it's Chinese novel? BL. Modern time. Start with ML supposedly saving MC from being a slave, MC seems really sweet and on the verge of being abused by a bad gang (maybe not gang, but powerful family). But MC is actually the head of the family, he faked everything because he has loved ML for a long time. MC waited at a restaurant all night for ML, who didn't show up. So he decided to take an alias and to act weak to get closer to ML. He's a power bottom. He even asks his subordinate if he looks cute and weak, and subordinate laughed it out.
ML asked him to marry him in grand way. Airplane jump? Side story, we have a flashback, young MC was saved by ML mother and as he leaves he crosses the path of ML.
It's a cute story overall, I cannot remember the title, but I really love the story, and I think it's a popular novel.
In all the lifetimes, he loved, loves and will love Aeroc, so unfortunate, only in his 2nd lifetime was he able to process that. If I remember well in the sequels, Kloff always tells Aeroc he loves him when this one has doubts.
