(Spring): stayed home during the day and would go to the mining lake at night to smoke. Thursdays will sometimes stay home all the time and sometimes go to the train station to smoke. Friday will play pool with Sam at the saloon after 3. On Saturday would go to Sam's and in the rain would go to the fish store dock.
(Summer): same as spring, but will go to the clinic on the 4th for a physical.
(Fall): stayed home during the day and went to the lake in the afternoon. Otherwise same as spring.
(Winter): same as spring.
Expanded:
Background: the most popular male NPC by virtue of his high face value, an otaku who spends all his days either in front of the computer or smoking by the lake, and occasionally goes to find Sam to get laid, has a rather negative personality, doesn't like to get in touch with people, and enjoys computerized motorcycles as well as rainy days. The gift is relatively simple, the trouble is how to find him before two stars.
The game only saves every day when you go to bed, and by 2am if you haven't gone to bed yet, you'll fall asleep right there. If you fall asleep outside the house, you will be sent home by someone from Joja's company or a kind NPC.
Also, when on Day 1, parts of Day 2 are actually determined, such as the number of earthworms on the ground, their locations, and the items that can be dug up are generated the day before, meaning that there's no way to take a chance by reading the file over and over again.
