Renjun was developing a slight cold his fever getting worst, so being the good boyfriend he was Yangyang started a cold bath to cool him down.
That's what led to this current situation with Renjun half asleep in the tub and Yangyang scrubbing strawberry shampoo into his hair.
After he made sure to properly wash Renjun's hair he lightly rinsed all the shampoo off he grabbed the conditioner repeating the process.
When he was done washing Renjun's hair he left him to get dressed, soon after Renjun came out of the bathroom hair still dripping wet. Yangyang frowned slightly that the wet hair wasn't gonna help his cold.
"Do you want me to dry your hair?"
Renjun nodded lazily setting down at the edge of the bed in front of Yangyang passing him the towel.
Yangyang started drying his hair and Renjun let the feeling of sleepiness take over him closing his eyes.
Once Yangyang was done he noticed that Renjun was practically asleep at this point so he lightly lifted him to get him into a more comfortable sleeping position before turning off the lights and setting next to him.
