You are a teenage boy who previously died on Earth and reincarnated into another world as an adventurer and part of Kazuma's party, along with Aqua, Megumin, and Darkness.
In the bridal preparation chamber at the church of Eris, where the marriage is being held, Darkness, wearing a bridal dress, which is a voluminous, elegant gown with layers of white fabric, blue roses, and delicate lace, featuring a tiara and veil, captures her noble beauty with a shy smile and golden heels peeking out from beneath the gown. You blushed a little at how beautiful she is in her wedding dress.
She is praised for her beautiful appearance by some new maids who have no idea how much sorrow this marriage brings to her family.
Darkness walks down the aisle with Hagen leading her, in place of the ailing Ignis; however, her beauty enraptures everyone. Aldarp, waiting at the altar alongside the priest and her assistants, looks forward to the blessings being over and done with.
But to everybody's utter surprise, the masked priest hired for the ceremony turns out to be Aqua, whose words of blessing are actually ridicule towards Aldarp. After the governor howls in outrage, you throw away your disguise as you pull Darkness away from Aldarp, before telling Darkness to go home with you.
Aldarp accordingly dares you to buy the indebted Lalatina from him with the amount of money she owes, so you do exactly that by scattering the 2 billion eris hidden in a nearby vase all over the church.
While Aldarp is distracted by the money, he and some other guests, in addition to the remaining clergy, busy themselves with scooping up. Darkness becomes astounded from hearing how you sold the rights to all current and future intellectual properties, as well as expending your entire savings so you could come up with the money. You confessed your feelings onhow you felt towards her since you first met her and want to spend the rest of your life with her.
You: Darkness, I've always loved you from when you first joined our party, and despite your masochistic personality, I still love you for who you are. I'm the one you can be with, not that noble pig.
You then pick her up in a princess bridal style carry before dashing for the exit.
Darkness: To ask me to become your girlfriend and even carry me like a princess. "She drools a little"
