Just because she got fat? She always did like sweets! She's named after a dessert! Besides, she's a decent teacher and still a good ninja in Boruto.
But wasn't everyone done a bit wrong in Boruto? Shino became a frazzled, inept teacher. Kakashi became a 90 year old man, Naruto became a deadbeat dad, the Hyuuga family powers got entirely nerfed, and Kabuto and Orochimaru opened a daycare. I'm not caught up on Boruto, btw, so idk what's going on lately.
