I read this yaoi manga, forgot the title though, where the last chapter have this scenario: The neko cannot express his love to the tachi and the tachi understands it and tells him not to pressure himself and it's okay to be spoiled. Then the neko suddenly bursted out in tears saying he doesn't want to be always the one recieving, that he wants to do something for the tachi too. "Even though I love you, I can't say it. How will I let you know that I love you!!!" That's the line of the Neko which I only remember so please do help me find this. Thanks in advance.

By the way, the Tachi said to him "Just like that. Message recieved!"
