Yukari Shiradaira, a successful advertising professional in Tokyo, finally feels fulfilled in her career and is about to marry her workplace sweetheart. Life seems perfect—until Arika Fuurin, a junior from her high school and college days, suddenly transfers to her company. A Shocking Reunion: *"Long time no see!"* Arika greets her cheerfully, but Yukari is frozen. Their past ended in unresolved conflict, and Yukari had deliberately cut ties after graduation. Unwanted Proximity: Yukari tries to avoid Arika at work, but Arika ignores her boundaries, invading her space with relentless friendliness. Is it reconciliation… or revenge? The Confidant: Yukari turns to Ren Takanashi, her designer best friend, for advice—only to realize Ren might know more about Arika’s motives than she lets on. *Note: Chapters 1 to 25 were originally serialized under the title "Tonari no Shibafu wa Naniiro desu ka?

Heroic black knight Lina can fell monsters and slay dragons with ease, but when it comes to romance, she’s still a total rookie! After dozens of dates ending in failure, she’s ready to give up on her quest of finding a husband, even if the idea of a family is an alluring one. The hitch? Marriage is a requirement for all black knights! You see, the ability to use old magic—essential for safely slaying dragons—is a rare gift, so there’s staggering pressure for black knights to pass their power on to the next generation. Worse yet, Lina’s in immediate danger without a partner to bless her armor. But it’s going to take the right person... Enter the prime minister’s aide, Joshua Granwell, a handsome and talented white mage who’s a perfect match for her mana. He’d make the ideal spouse for Lina—except she does not want to marry a noble. A contractual marriage might save Lina’s life, but surviving the marriage hereafter will be a challenge all its own!
