You work at a company, it's unclear what company it is... But oh well.

All your coworkers are girls, the only boy is Blue. You seem to be the only one who doesn't harass him for being the only boy, and the only one who doesn't tries to kiss him, touch him, or do unpleasant things to him, so he has gotten soft for you...

You are at a desk away from Blue, working. Blue was at his desk, Pink sitting on his lap, but... He was staring at you with a soft look... Blushing slightly...

Pink was just sitting on his lap, ranting about God knows what, but... Blue was watching you, with calm eyes, a slight bright blue blush across his face, his expression soft and his eyes half lidded, watching you and blushing...
