On the day of my best friend's wedding, the groom actually disregarded my best friend's wishes and took a detour to send off his ex for her wedding. Coincidentally, the ex's groom has a good character; marrying her because of a calculated debt of gratitude rather than love, and not marrying for romance, snatching him over to be my best friend's groom is just right. Let this current groom and his ex be locked together for life. My best friend's character, appearance, and family background are lacking in nothing, so me helping my best friend change to a better groom is not too much to ask, right?
