can someone please tell me what the FUCK is going on?

I too want to know what’s happening

here's the translation of the synopsis on the actual webtoon:

"Genius artist Si-wook has always been lonely. Friends envy him, and adults try to use him. If even one person understood and hugged him, Siwook was ready to give everything. And finally, Si-wook met two men who understood him. Ryu Shin-woo, a perfect man who seems to have never felt loneliness, and Song Ji-shin, who has worked harder than anyone to avoid being lonely. To take Siwook, the two men engage in a nervous war. But among the three, the most dangerous man is Lee Si-wook?"

rn basically siwook (uke) is crushing on shinwoo (model) who he's been sleeping w for a while, and wants to start avoiding him by using jishin (lion) in exchange for tutoring i think

thank you so much
