Anyway it looks like a nice manga with a lot of ecchi chapters and the MC being in costant fear of his freedom.
As MC doen't react to girls it looks like the other one will suffer a lot, unless she learns of his weakpoint.
Lind not having a homee for the debt is not totally realistic, the aunt probably adopted her to use the granfather belongings to pay her debt and her house was taken away...then what? Where was Lind living? She could go around with a cosplay set and spend money on a figure but not had a stable roof? Transfer to the school and then what, go live under a bridge?
