Expert Tips for Maximizing Your Happy Summer Experience

Time Management: Each event and dialogue trigger is bound to specific day parts. Missing the right time window means waiting a full day cycle. Use an in-game or external schedule tracker.

Relationship Balancing: Focus on one character at a time to avoid missing unique events, especially during level-ups when new scenes unlock.

Exploration: Always check rooms thoroughly, especially during morning and daytime parts. Key items like statuettes and books unlock major story branches.

Money Management: Keep enough funds to cover both gifts and rent to avoid unwanted setbacks.
