Who Is a Sickly Girl Who Walks Her Dog Every Day?

[Double male protagonist + double cleanliness + double strong + yandere + he ] Li Zhi, who has lived in Iceland for a long time, fished up an alpha from the glacier. The alpha is very beautiful and looks very much to his liking, so the bored and yandere Li Zhi seduces him. Every snowstorm night in Iceland, Li Zhi would whisper in Alpha's ear: "I love you." After talking for so long, Li Zhi himself started to believe it. However, he still killed the alpha with his own hands, threw the alpha in the snow and ran away. Before running away, he even mocked the alpha. Half a year later, Li Zhi appeared in front of Alpha again. He was pressed on the desk by Alpha, and his shoulder blades were almost crushed. (It's probably a story about a boring Omega who seduced a boring Alpha, and then the Omega tried to kill the Alpha but failed, but the Alpha stole the experimental data, and half a year later it was a short story in the crematorium.)
