El Más Joven Esconde Muchas cosas.

A child-soldier mage regains memories of a past life on the battlefield—and realizes this world is a novel with a doomed, apocalyptic ending.
To avert it, the plan is simple: stick to the story’s “hero” and keep him alive.

After some twists, the narrator sneaks into the duke’s household as the adopted youngest.
One problem (actually three): the hero hates mages, the narrator is a deserter, and a messy mix-up has them living under a swapped-gender disguise.
Now it’s constant tiptoeing to avoid being found out while plotting how to protect the hero… and somehow there’s always time for strawberry cake.

A cozy, chaos-filled tale of a secretive “maknae” with a lot to hide.
