I think this book was bl, all I remember a scene where the eunuch was sent to deliver something to a concubine and was made to stand outside in the rain then the emperor found him and stood up for him. Help!!
I believe that's in I'm squattering IQ to the protagonist If not, perhaps in There Will Always Be Protagonists With Delusions of Starting a Harem
Baldingere is correct, it should be "I'm scattering IQ to the Protagonist" Arc 3: Scattering IQ to the Lonely Emperor (Ch. 39-56b) The scene you're describing is in Ch. 41 (MC standing in the rain, seen by ML) and Ch. 42 (MC "fainting" in the rain and picked up by ML who just came out of the consorts palace.)
