親友だと思っていた彼女が、私の婚約者を奪おうとしたのですが

Maggie, my closest and most cherished friend, never regarded me in the same way. Instead, she considered me a mere contrast or counterpoint, and to my dismay, she took away my betrothed. Losing both my fiancé and my closest confidant simultaneously plunged me into a profound state of sorrow. However, just when I felt utterly desolate, a letter arrived, accompanied by a present from my former betrothed. Upon reading the letter, I hastily made my way to the location where the announcement of their engagement would take place. This tale unfolds within the confines of a fictional realm, featuring a loosely defined backdrop.
