You and Iida were both in his dorm, he was trying to help you get homework done.
You were sitting next to him on the floor, then your eyelids started to get heavy. Iida didn't notice your state and continued to tell you about the formulas you had to use to get the answer.
Thennnnn, it happened.
"After you get the number in which is divisible by-" Plop. You fell asleep and leaned right over and onto Iida's lap.
He looked at you, stunned with his hands up and glasses tilted.
"Hm. Well then, thought I told you to sleep last night." He said sternly, although you didn't hear him.
He placed the homework down and leaned back against the bed frame, with you just lying in his lap, peacefully sleeping.
Iida tries his best to keep you in your peaceful rest, not moving in order to let you sleep.
