Give the first gift to unlock meal invitations
Give each intended support target a gift to unlock meal invitations. Once the chapter begins, visit the inn restaurant and invite them. Sharing a table raises several relationships simultaneously. Choose a chapter that reaches free time quickly and has plenty of turns for an easier loop.
Chapter 7 on 
Leda’s route works well. Free time begins immediately, without a battle first, letting you go straight to meals.
Eat each week, then restart the chapter
- 1Invite the target character to a meal on Sunday.
- 2If at least a week remains, use Auto-earn to advance 28 turns to the next Sunday.
- 3If less than a week remains, select Restart Chapter in the system menu.
Meals still cost money. Restarting keeps Support experience but returns gold to its chapter-start amount, allowing you to reuse the meal money.
Match dining groups to recruitment requirements
Support is shared across routes, so this loop can prepare future recruitment. Everyone at the table builds relationships together. It is more than the bond between the protagonist and one target. Identify the relationship group you need, then invite them together instead of buying separate meals without a plan.
