@riinflorida There's a good chance that granny would stop more direct attempts for Rakan to redeem her. Maomao did something that was still excusable as helping the group as a whole, while everyone else was constrained by courtesy to allow him the choice. Forcing someone on him could have tipped him off or given him ammo to refuse and cause a lot more problems.
Granny definitely doesn't trust Rakan and believes Feng Sheng's current living conditions were the best for her(yeah right). Maomao had long since confirmed Rakan's sincerity, so the only step left was to create a ploy to get them together.
That being said, this is going to make the future a lot weirder since the WN had Rakan travel all over the place and he now has very good motivation to stay at home all the time.
