This is a collection of Sulu/Chekov shorts, but not all of them are romantic, and not all of them have happy endings. Just a warning. Also, I'm pretty sure that none of them are in a common universe, or correlate to each other in anyway. They switch narrators a lot, so be ready. :)

"Lips of an Angel" – Hinder
Why was Pavel suddenly coming into his room at two o'clock in the morning? And why, pray tell, were his cheeks stained with tears like that? The younger man sniffled and climbed up on Hikaru's bed, uninvited, and curled into a ball next to his best friend, shaking like a leaf. Another night, another nightmare, Hikaru thought sullenly, patting his friend on the back lightly.
"Why are you crying?" he whispered, though he already knew the answer. Pavel looked up at him with big, blue eyes and pouted pink lips that were just so alluring that Hikaru almost had to look away. Then he licked those lips and opened his mouth to say something, and it was absolutely mesmerising.
"Hikaru..." he said all-too-loudly. Hikaru winced, even though hearing that voice, saying his name in that way that was just so sweet.
"Pavel this really isn't a good time—"
The young Ensign who was now standing in the doorway to Sulu's bathroom with her mouth open, wearing nothing but a towel wrapped around her body, would have to agree.
