The Imperial Guard with a Saber

Quiet, long-haired transmigrator gong VS talkative shou who seems impatient but is actually a sweetheart

One-on-one

No love rivals, male or female, no stand-in trope, just a match made in heaven, destined for each other!!

Transmigration + a touch of past lives

Theme: As long as you're happy, that's all that matters
