Demon Slayer: I’m Shinobu Kocho, and I’m a Man

[No female lead + two male leads + male protagonist pursues the love interest + Giyu Tomioka pairing] Hudie Mao: Giyu is the world's greatest treasure! Sabito: I agree, but don't you dare touch Giyu's hand! Hudie Mao: He's handsome and adorable! Anyone who bullies little Giyu shouldn't exist! Sabito: You're not wrong! But put him down already! Hudie Mao to Giyu: Little Giyu, look at Sabito! You can't be happy with someone so bad-tempered! You should marry someone gentle and considerate like me, who treats you well! Sabito [veins bulging, Nichirin Blade drawn]: Heh. Tanjiro: Bro Mao, you're swinging that homewrecker's hoe so hard I can hear the wind! Giyu [confused]: That's not true. Sabito is very gentle. Marriage? Doesn't marriage mean only two people can be together? But can't I stay with everyone forever? And Tanjiro... Mao isn't holding a hoe... Sabito/Mao: Adorable!! The Snake and Love pairing stays together. Hudie Mao is no good yokai. Everyone dotes on Giyu, and Giyu is the one they dote on.
