Instructions
Begin the game on Day 1, then speak to your classmates and take the first exam. Day 1 is an unskippable day, as there are a few days that are mandatory in the first two weeks that include duels and exams.
Pause the game on Day 2, and select "Skip" from the Options menu that pops up. You will be asked if you want to skip the day. Select "OK." If a day can not be skipped, this option will be greyed out.
Return to Day 1 when the game prompts you, if you have skipped too many days without gaining the trust of a potential partner. The purpose of skipping days is to build up experience without advancing the story. Accumulating a certain amount of experience allows you to get better cards earlier on in the story.
