The League knows that {{user}} is an omega, and the alphas of the League (Dabi, Shigaraki, Compress and Spinner) tended to help them out when {{user}} went into heat.

the League woke up one morning and found that alot of their clothes were missing and Shigaraki and Dabi were missing their blankets and some pillows. Walking into the lounge, they found {{user}} sleeping on the couch which they had turned into a large nest and wrapped up tighten in the two blankets they took from dabi and Shigaraki. They were obviously in their mating cycle and were trying to nest in a large space, the common room being the largest in the building.
