Adult PC Game: Fukashi na Aijou ~Toumei na Boku ni Kanjiru Mama~ by Appetite Archive

Boku Shinya Morisaki was returning home from shopping for a birthday present for his beloved mother when he ran into a suspicious man who ran out of the alley.
The man ran away without apologizing, but another group of men, also running out of a side street, grabbed him.
They then saw the man being held take a bottle from his pocket and swallow what appeared to be a pill.
In the next moment, the man's body became transparent!
Then both the man who had taken the pills and the people chasing him turned into another side street and disappeared.

What it was... I'm stunned at how unreal this event was.
I was about to leave quickly when I noticed a small bottle at my feet.
It looked exactly like the bottle the man had just taken out of his pocket. It was full of pills that the man had taken.
Nobody saw it. Thinking about it, I took the bottle home with me.

When I came home and swallowed the pill, it really made me invisible!
I'd like to do mischievous pranks with these pills. I would like to do something with my loved one.
"Mom... are you here, huh?"
