After Chisato's childhood friend and secret crush, Tsunayoshi Sawada, confesses to another girl, she inexplicably awakens memories of her previous lives.
In every one of those memories, she and Tsunayoshi Sawada meet a BE ending.
And now, it's the day after everything starts to go wrong, just like every time before.
Chisato thinks things over. Once she's sure her past lives weren't just her imagination, she makes the following decisions:
1. Help Tsunayoshi Sawada win over his beloved girl.
2. Get close to that villain and stop him from going berserk and destroying the world.
3. Convince the Vongola, especially Tsunayoshi Sawada, to approve of her and the villain getting together... No, to bless their happy marriage.
4. If she can't do any of the above, then let ze?tian?gang?ji
Friendly reminders:
1. CP: Tsunayoshi Sawada
2. You can consider it another honeymoon trip for Chisato from a different world.
3. A traditional HE. No BE or OE.
4. The author is a total weirdo. Just look at their other stories. The style is old-school~
