Song Lang binds himself to a confession-mission System.
In every world, the mission target has secretly loved him for years, yet refuses to confess until death, leaving behind a lifetime of regret. Song Lang must break through the barriers and confess to them to achieve a happy ending.
In the first world, Song Lang transmigrates into a prince. His mission target is the aloof tutor who has taught him since childhood.
A social butterfly, Song Lang adds something to the tutor's food. When the wine has gone to their heads, he draws the tutor into his arms. "Could we take our relationship beyond that of student and teacher?"
The tutor's cheeks flush and his breathing turns ragged, but he bites his lower lip and stiffly pushes Song Lang away. "The bonds between sovereign and subject, teacher and student, must not be cast aside."
From then on, after class, the tutor teaches the other princes and no longer speaks to Song Lang.
Song Lang: What happened to secretly loving me?
Song Lang starts pursuing the tutor. Just as the man is beginning to fall for him
The tutor is suddenly thrown into prison, and all the princes who associated with him are implicated. Song Lang is unexpectedly named crown prince.

For a man about to die, love is an extravagant luxury.
Song Lang doesn't know that the mission targets in every world are all deathsworn, ready to sacrifice themselves for their cause at any moment.
They desperately push away the people they love so that, after they die, Song Lang can have a bright future.
