I believe Maeve Auclair is a good candidate as a possible partner for Qiu Lin for multiple reasonings as following:
In step one Maeve's personality is shy and quiet and always looking out for Qiu. Qiu is the main reason why she likes Golden Grove in the first place and how she got settled down, without him I doubt she'd have the same experience and enjoyment as she did. Qiu slowly pulled her out of her shell, and if she didn't she would still be with her mother inside to this day. Maeve looked up to him, a lot, she felt safe around him, and followed him along like a lost puppy for the most part, as she was still getting used to everything else in Golden Grove
In step two Maeve's personality is a the same, but she takes more of an initiative, 'courtesy of step 1 Qiu Lin'. She gets them up and moving out the door to touch grass, she (sometimes) entertains Qiu Lin's dramatic episodes, but in the end she's empathetic and understands they can't stay inside all day (because that's what she wanted to do all of step 1) and as such she was able to coax Qiu out and ensure they're healthy, happy and enjoying himself. Even if it means pulling Qiu out of they're hiding place. She's understanding and sympathetic, and somewhat understands how Qiu feels, that's why she tries so hard to make sure they feels appreciated and understood.
Step 3 Maeve has become independent, she doesn't rely on people, not anymore, but still retains her gentle, soft demeanor. She's able to make her own decisions, and has more of a playful attitude towards her friends, she's caring towards them and somewhat acts as the 'mom-friend' as she's always looking out for them. She's stable and understands what she wants to do in the future, and has a clear plan of how she's going to achieve a stable income, in which she's able to support Qiu Lin if they do choose Maeve as a partner. She loves Qiu Lin a lot and wishes to support them in his endeavors, and ensure that they has a happy life, with whatever they choose even if it's not her.
That is all your honor
