My first story :) please give feedback so I can improve (MM)

It is a cold night sky in the city, not much people are present in the streets. Aren and Eren are walking at the pavement at the left side of the road, going home after their college tuition. They hear only their footsteps, and the sound of engines time to time. Eren is tired because of helping Aren carry his books and started panting soundly. That caught Aren’s attention.

Aren likes the sound that Eren is making, and try to hide it. Eren glance over to Aren and his face is slightly red. At first, he thought it’s just from the walking. Aren starts panting faster and his cheeks become bright pink because of the walking. Eren noticed it and his face turn bright pink as well. Eren felt suspicious of him as he is not panting at all. He tries to ignore it and pulls out his phone to check the time. But as he glances down, he saw something weird about Aren’s pants.
