The Sparring Match
The previous chapter ended with a high-tension moment at the training grounds. Cassian, the most skeptical of the four brothers, witnessed the protagonist’s ability to stabilize his mana overflow during an intense sparring session.
The Silent Acceptance
For the first time, one of the brothers offered a genuine “thank you.” The chapter closed on the Duke watching from the balcony, realizing that the “contracted daughter” is doing more to unite his sons than years of mediation ever could.

The Eldest’s Vow
Chapter 17 is expected to show the eldest brother, Mikhail, taking a formal stance. Spoilers suggest he will gift the protagonist a protective artifact, signaling to the entire household that she is now officially under his personal protection.

A messenger from the Imperial Palace is predicted to arrive in this chapter. The contents of the message will likely force the Duke to reveal the protagonist’s presence earlier than planned, setting the stage for a confrontation with the social elite who view her as a “commoner intruder.”
