For all the people asking if this was real or a dream or if its supernatural, the title of the work IS "Love Gives Me Superpowers" so I think it's safe to say this is one of her powers.
I think it's so funny that this comment section is full of people telling Kon to ditch Ai and find a better girl, when that's exactly what the MC in Brides of Iberis (by the same author) and everyone hated it.
