Imagine Person A of your OTP listening in to Person B singing in the shower.
"Singing in the Shower"
Rango sat on the bed, smiling softly as he listened to his boyfriend singing in the shower. It wasn't every morning that he got this chance. Usually Jake was out of the shower just as he woke up.
"Masquerading as a man with a reason, my charade is the event of the season. And if I claim to be a wise man, well, it surely means that I don't know." He giggled softly as he listened to Jake signing one of his favorite songs. "On a stormy sea of moving emotion, tossed about, I'm like a ship on the ocean. I set a course for winds of fortune, but I hear the voices say,"
Rango joined in for the chorus at this point, "Carry on my wayward son. There'll be peace when you are done. Lay your weary head to rest, don't you cry no more, no!"
Rango smiled and chose that moment to get up, get dressed, and go make some breakfast for Jake as the older man finished up his shower.
