  Summary

  Between Vongola paperwork, diplomatic disasters and increasingly rare nights off, Tsuna's love life has narrowed down to anonymous hookups which have made clear that his type is tall, dark-haired and preferably with a large ego.

  Reborn has spent years cataloguing exactly what Tsuna looks for in a one-night stand and years longer wondering why none of those men were ever him.

  Tonight was going to change that.
