Escape from Beast House

It was a hot summer day...I believe it was after swimming club activities. As a freshman, I was going to visit the house of Tadokoro-senpai, who was very kind to me. Of course, I was accompanied by Tono, my best friend since entering the school, who is also a member of the same club.
Tadokoro, a senior member of the swimming club, is famous for his insistence on time, always asking, "Hows your time? Have you improved? Has it not improved? ......" Because he called out these phrases every day, some of the senior members shunned him as a "serious and dedicated guy," but he was appreciated and adored by most of the members. I guess you could call him a "fresh leader" nowadays.

By the way, the act of playing at someones house after club activities was itself an unusual occurrence hidden in everyday life, and we went there purely for fun, without thinking too much about it.
........
I should have realized at that time.
I should have realized at that time why that shy senior invited us to his house.
Why he was so strict with us, but so lenient with us...
I should have known that he, my best friend, and myself would not have been in such a mess.
I wouldnt have had to go through all that...

Prologue
Coma.

Fah!

Fa! Umm...

Did you sleep and ......?
My head is throbbing.

........

Where am I?
Yes, I am. Im pretty sure I came to my seniors house for a visit ....

Then I think I had some iced tea on the rooftop.
I was in a strong drowsiness .......

What are you doing? Please stop! Im serious!
I heard a shout.
Tono! That high-pitched voice was probably him.
Hes scared of something.

If we dont do something, well be in trouble.
We have to get out of here first.
Lets find a way out.

Stage 1.
The room with the big pillow.

Stage 2.
The kitchen with the aroma of iced tea.
