Feeling guilty for my fellow passenger

So I was going back home after completing my work in college. It's been a month since I went to home. My hometown is in karnataka 4 hours away from Bengaluru. I initially took a bmtc from college to majestic which took nearly more than an hour. Then took a ksrtc bus to my hometown. I sat in the window seat as I always did but the time was around 12.40 pm. As we left bengaluru the sun came right against my window. Along with the hot weather now I had to suffer sunlight against my face for four hours. A lady sat right next to me who closed the window right after she sat. So after she slept i opned the window just a little. Believe me when I say I was cooked, I tried finding other places to sit as I was being cooked. I asked the person infront of me if the seat was empty and he said no. Then the lady beside me proceeded to close the window yet again. Which made me open it after she slept. I wore my cap and hoodie cap trying to not get sunburnt while kept air flowing through the window to cool down. I stood up as I knew it was still 3 hour journey to save myself but there was no seat. I sat down while the lady kept on sleeping. But few minutes later she stood up and went to sit in the front seat of mine. Am I the asshole here trying to save myself from the heat? The thing is the windows are glass and the sunlight kept coming from the upper window while I kept the lower wi dow open for air.
