UToradora is legit the best romance anime hands down on it. Thank god I'm not the only one who thought about that.

Well if you really want something similiar to it, I would recommend a few but it's just not really "similiar", as anime series itself are unique in their own way, including Toradora.

Here's a few I find it enjoyable: (In Romance genre)
Hataraku Maou-sama!
Hidan no Aria
Hentai Ouji to Warawanai Neko.
Irozuku Sekai no Ashita kara
Kokoro Connect
Masamune-kun no Revenge

I’m also glad I’m not the only avid Toradora fan here :D
Also I’ve watched Hataraku Maou-sama and Hidan no aria i’m Looking forward on watching those you’ve recommended!
