Ending Outcomes for Mystic Messenger 707

Like other characters in Mystic Messenger, 707’s path includes multiple endings. The previous sections outlined his Good Ending sequence, yet for those interested in exploring alternative outcomes, here’s a quick guide:

• 707 Normal End: Complete the party with 0-9 RSVP emails opened.
• 707 Good End: Complete the party with 10 or more RSVP emails opened.
• 707 Bad Story End 1: Select inaccurate choices (blame 707 for security breaches) leading up to Day 7.
• 707 Bad Story End 2: Make correct choices through Day 7 then shift to wrong answers that overlook 707’s emotional struggles through to Day 9.
• 707 Bad Story End 3: Continue with correct answers through Day 9 and switch to incorrect ones (doubt 707 or side with Saeran) leading into Day 10.
• 707 Bad Relationship End 1: Attain below 30% chat participation or acquire fewer hearts for 707 compared to others from Days 5-7.
• 707 Bad Relationship End 2: Pass Day 9, yet score below 30% chat participation or gain more hearts for other characters over 707 from Days 7-10.

With strategic use of saves, you can efficiently navigate through all these endings with one journey through 707’s route. Remember, it will require a total of 20 HG to reload your save multiple times. Ensure you’re familiar with the saving rules before proceeding! Here is the most efficient approach:

• Do not open RSVP emails (those received after three correct replies).
• Make a manual save after reaching Day 5, then achieve Bad Relationship End 1.
• Reload your save and achieve Bad Story End 1.
• Reload your save again and achieve Bad Relationship End 2.
• Reload, proceed to the Day 7 branching point, create a second save, then achieve Bad Story End 2.
• Reload the second save and achieve Bad Story End 3.
• Reload the second save, now achieve Normal End.
• Finally, reload the second save, open all RSVP emails, and achieve Good End.

The walkthrough above provides insight into securing 707’s good ending. Should you desire additional direction on navigating to his bad endings, simply reach out! What lies after this is the continuation of 707 and Saeran’s journey within the Secret Ending—a chapter demanding considerable HG investment to unlock every episode!
