I can imagine a "my hand's in a cast, please help me lift this box" sort of setup, but building a relationship is a bit ambitious. Dude's gonna recognize that something's off, and plan around it.
Honestly, in this manga, it's hard to tell if MC is just actually dense to romantic advances, or is just actively ignoring them. So he might be able to tell it's bait pretty quickly.
To be honest, the artist can really draw beautiful and sexy girls. All the girls in this manga are beautiful. Also i bet she's going to fall for the MC first lol
If anything she will fall for him for real but still lose to the shorter haired co-worker from the workplace. Just like their spiritual predecessors from Tenohira ni Ai wo! lol.
