Thankfully, Shen Tianyu's class was on the third floor so she didn't need to walk all the way to the top, not that the third and fourth floor made much of a difference.
Though she always inherently felt the topmost floor of a building, especially wooden buildings with no air conditioners were the hottest. Maybe it was a psychological trick of those floors being closer to the ball of destructive fire known as the sun?
She found her classroom to be in the middle of the long hall, where it wouldn't be the brunt of sunlight in both mornings and late afternoons. With a light mood, despite knowing who else would be waiting inside, she opened the door and entered in a polite manner.
