Half naked

Don't know why recently it was quite hot. So whenever Ethan comes back from school, mother takes out all his school uniform and only left the underwear. He is doing his homework half naked as mother found him sweating a lot when doing his homework. Mother doesn't want him to sweat a lot as he needs to take a bath after he finishes all his homework.

At first, mother is a bit worry whether he will get sick in this situation since he is never naked like this at home before. So far so good....
