Yang Fei was indeed a bit calculating.
He was single-mindedly thinking about getting Qin Yanyang completely under his control, taking her body, and capturing her heart.
However, Qin Yanyang had been on her guard against this from the start, so even though they slept in the same bed, with Yang Fei trying every soft and hard tactic, doggedly persisting, in the end, he still didn't succeed.
Force was not an option either, after all, Qin Yanyang was no weak woman, and even though Yang Fei's strength now slightly surpassed hers, such an act, if forced, would be more difficult than Yang Fei attempting to slay someone in the Innate Realm.
The deed wasn't done, but Yang Fei did make progress with his soft approach, hard nagging, managing to wear Qin Yanyang down until she went to sleep at two or three in the morning.
When he woke up the next morning, the sun was already shining on his butt.
