Help with the wrong name of the pervert and the ending

Aina took care of a man squatting near her house who was suffering from a heatstroke. The man's name was Kamiya, and when he learned that Aina was a welfare office worker, he confessed that he was unemployed and asked for help. Aina, who always cared for others, could not abandon him and sought advice, but Kamiya, who had misunderstood the kindness that had moved him for a long time as kindness towards himself, suddenly developed an attraction to Aina.
