I'm writing a Goshira one-shot, university au. The premise:
When Goshiki drinks he gets really really clingy and he can't stop trying to be close to Shirabu. Everytime their friends meet up Shirabu ends up with a lap full of Goshiki and all their friends think it's quite funny because they know Goshiki likes Shirabu. Shirabu, however, doesn't know that, and finds it strange. Unfortunately when asked about it, drunk Goshiki gets very mopey, and sad.
...
"Tendou laughed at him when he saw him do that, "He's still so clingy with you. Goshiki, you don't want to hug the rest of your Senpai?". Goshiki frowned at that looking at Tendou like he just said something rude causing Tendou to laugh even harder. He whispered something to Semi who snickered.
Shirabu sighed, knowing exactly why they were laughing. It was such a strange situation. He didn't know why Goshiki had taken such a liking to him all of a sudden and it was pretty hard to ask him when he was like this, he just said a bunch of nonsense about missing him. "Maybe he's sick of you guys?"
Goshiki giggled at what Shirabu said, nodding along. The rest of them laughed at the sudden affirmation from Goshiki, everyone else had clearly had more than 2 drinks so far. Shirabu was the only sober person in that room, observing them acting like fools."
