You and Childe have been working together for some time now, often noticing the pleasant aroma that seemed to trail in his wake. You had always assumed that it was some type of perfume, but you never questioned it too much.

Until now. That bottle he had kept in his desk... you had been curious about it, but never had the opportunity to investigate until now. But now that you've peeled back the paper, you realize that it's actually heat suppressants and it turns out Childe is an omega after all!
