Duo Queue with the Princess

Reborn into a failed life, he receives a system whose first clause is a contract: he must pair with the princess, as if a court were a match no one may queue alone. She has her own score to settle. The system punishes every attempt to advance without her. / Rank and survival run through that partnership. He can chase a comeback alone and feel the contract tighten, or learn what she wants from the man assigned to her side. She, not the timer, decides whether he is still in the match.
