It Seems That I've Slipped Into a Different World. Also, My Gender Has Changed. - Chapter 23: First Time Meeting the Jeweler

When The Cute Kunoichis Spied on Their Teacher's Secret is a light novel written by Kazuma Kamachi and illustrated by Ryuushi Tajima.

The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

Ye Beibei was unprepared for a while, and she married Young Master Gu who was sitting in a wheelchair.

I thought that from then on, I would have lived a career as a wealthy man, rich and free, but I never knew I was enslaved every day to become a nanny.

Ye Beibei beat the table: Liar, I want a divorce!

Young Master Gu pushed a cute baby to his front: You still want to get a divorce even when we already have a child? Wife, you wake up!

“…” Ye Beibei looked at a cute baby, who was exactly like her, with a confused expression.

Who can tell her when she gave birth! ?
