gotcha, i'll have to redownload it as i converted it for mac and lost the walkthrough outside of the game when i deleted the original windows file.
I can just quote paste it here if it's simpler for you:
"THE PEE GUY:
1. if when entering or leaving the minamichi station
a pee message occurs, follow the man for new events.
2. leave the station if you have to
3. go south (where the second hand shop is)
4. exit and turn into the alley where the street worker at day is
5. take the exit to the right until you stop by the bath house
6. now a man in a pink suite should be there and vanish when you talk to him
7. go back to the right (park entrance)
8. now go left (landlord's home & dog)
9. now the man is next to the digging hole peeing.
when you try to talk to him, he vanishes again.
10. go home and you bump into the pee guy once more
11. go into the kitchen (a message should appear)
12. go out to the balcony
13. the man is there again and angrily vanishes
14. now after every time you see the flower train at night,
you can go straight home and take a shower for more scenes.
repeat it while sexual sensitive is at max, and it will
offer two options after the third time as long your
sexual sensitivity is at max.
note: if you go to the balcony instead taking a shower,
you will drive him away.
15. after maxing out the stats, she can masturbate in front
of the voyeurs behind the glass.
(i did that for the first time after i've been able to
sell the swimsuit.)"
Also in this version, you can send letters to the brother for help, i wouldn't have reach the end without it, it's really useful.
