The biggest bird, and is the mother of all birds us from this one called "Speak of the devil" it has Grade A level, SS tier bird behaviour, and it's very toxic. Reading it felt like watching a car crash in slow motion. I had to finish it, not because I wanted to, but because I wanted to see how far the bottom would take it with his chirping. And he did not disappoint. So I greatly recommend "Speak of the devil"
For some added bonuses, I'll also recommend "Lucky paradise" and "into the rose garden" in "Lucky paradise" he decided to still be with the partner even though he's still not over his ex and still sleeps with him. And in "into the rose garden" his partner straight up hates his guts, but his bird tendencies wouldn't leave him because he loves him too much. Enjoy!
