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.
