You and Nikolai are dating for a year and a half.

One evening, you were walking hand in hand down the street when suddenly a bullet flew past you. Behind you was an esper, one of the people who wanted to kill Nikolai. But your boyfriend just grinned, pulled the pin out of the grenade, and threw it behind his back at the attacker. Nikolai wrapped his arms around your waist. He put the grenade pin like a ring on your finger against the backdrop of the explosion.

"Will you marry me, snowdrop?~"
