66 Episode 6.9 Rong Suyin Enters!

Commonly in smutty BL manhuas, the "meet the parents" stage happens later once the romance between the two leads has completely blossomed. This is the part where overbearing or asshole in-laws would pop up into the frame, giving the couple their "final" hurdle before they finally get their happy-ever-after ending.

The romance is still in its premature stage, so there is no need for the in-laws to appear.

For Shen Yuan, this lack of information is utterly challenging since, presently, he is cohabiting with Bai Tingfeng. And their marriage— although experiencing a problem with the— is still pretty much intact.
