Can someone help me? Find this?

I found out about this manhwa that got on my fyp. The blonde haired seke and black haired uke, the black haired uke like the seke and stalked and him for years. Jerking off his photos and everything, one time during an event or something like lecture. He accidentally passed the USB with the seke's naked pics and porns, he snucked into the seke's room and planned to get the USB ang leave. Unfortunately he got caught because his ass couldn't fit in the window, the seke banged him and letter he found out that the seke's also been obsessed with him watching him jerk on his pictures and has a lot of videos of him.
Please I want to reread it, I still haven't finished the manhwa.
