I read this manga where the uke and seme are sex friends but they like each other. Then seme give the uke a ring but uke doesn't like accessories, but for the seme he asked a friend for a chain to put the ring to wear it. The seme found out that the uke accepted another person's chain while not knowing the uke used the chain for his ring so he got jealous.
I dont remember the name and I been looking for it, hope someone can help me （/TДT)/
