Fireworks and Everyday Life (The Bickering Couple)

Republican-Era Arc (Past Lives): Macabre Loli x Loyal Warlord (fantasy romance). Legend has it that there are man-eating demons who kill on a whim, and mortals who fearlessly fall in love with them.

Modern Arc (Crime Mystery): Girl Detective x Tsundere Forensic Doctor (crime mystery). Every murder case unravels thread by thread, revealing a love from a past life that was never brought to a close.
