Shakkin Reijou to Hikikomori Ryuu Ouji Senzoku Osewagakari wa Kiken ga Ippai!?

Corne, the daughter of an earl, finds herself burdened by a heavy financial obligation that threatens her standing. Determined to settle this debt and reclaim her future, she accepts an unusual position within the royal household. Her new role assigns her as the exclusive caretaker for Melvin, the kingdom's second prince, placing her directly at the center of palace life and its unspoken expectations. The arrangement initially appears straightforward, but the dynamic shifts dramatically during a quiet moment when Melvin is entirely under her supervision. In his vulnerable state, Corne inadvertently uncovers a startling truth about the prince that defies his public image. Far from the poised royal figure the court assumes him to be, Melvin is actually a profound recluse who harbors a deep-seated inability to trust those around him. This unexpected revelation transforms Corne’s simple duty into a delicate and unpredictable challenge. Bound by her need to repay her debts and now entrusted with the prince's most closely guarded secret, she must navigate a relationship fraught with hidden dangers. As she steps further into his isolated world, Corne quickly realizes that serving as the sole attendant to a distrustful royal will test her resolve in ways she never anticipated.
