I'm looking for a shoujo manga with a love triangle, preferably one girl and two guys, but where all the characters are portrayed sympathetically. So no asshole bad boy vs. nice guy childhood friend and no toxic jealousy and animosity between the two guys (friendly rivalry is okay).

I'd really like it if the guys are actually friends with each other and not just know of each other because of the girl. The girl does not have to romantically reciprocate both of the guys, but I want her to at least care about them.

Some examples of what I'm looking for would be Orange (TAKANO Ichigo) or Akagami no Shirayukihime where it's clear that one of the guys is in love with the female lead, but he's also friends with/cares about the other guy.

Jiujiu
Mekakushi no Kuni
Arakure
Penguin Kakumei
Bokura ga Ita
Adventure and Trouble Diary
Ano Ko no, Toriko
Akuma to Love Song

DONDAKEE!!

Cat Street - it's one of my favorite, and probably one of the most natural seeming love triangles I have read. It's not dramatic, kind of like Orange in that sense.

Thank you both for your suggestions! Already started to read a few of them and I like them so far!

Naui Binaneun Segye
Watashi no Ookami-kun
Tsubasa to Hotaru

Thank you! I will check them out!

i am a fan of stories with love triangles (one girl and two guys) and reverse harem (which is actually like a love triangle only two of the guys have a chance) so if you like my recommendation i know more mangas like this.
Short Cake Cake (in this manga the guys and the girl are adorable)
Haruiro Astronaut (very cute manga)
Hajimari no Natsu
Honey Buddy
Ouji to Hero
Renren Zakari
Momo Lover
Shinobi yoru Koi wa Kusemono
Wonderwall by Senaloli (this is a webtoon if you keep reading it becomes very sweet)

Obaka-chan, Koigatariki
Yume Miru Taiyou
Cherry Boy, That Girl
Kimi ga Suki

Wow, thank you!! Several of these look really great! I also really like love triangles, although sometimes I find myself getting annoyed with how they are written. Like I can deal with jealousy, misunderstandings and indecisive heroines sometimes, but some shoujos just way overdo it, haha.

If you want to, feel free to leave more recs, I'm not that picky and I'm always open for suggestions!

Quote from LazyCat3

360° Material

Really? I didn't find the other guy to be likeable at all.

He almost destroyed Taki and Mio's relationship. I mean, him going after Mio if she was single would have been okay, but she was already dating Taki. And he was super douchey about it too. Yeah, Mio gained feelings for him because he was nice to her, but it was still super intentional. She also started to doubt herself and was afraid she would do it to Taki again.

As for OP's request:

B Gata H Kei - It's minor, but there's a slight love triangle between Yamada, Kosuda, and Miyano. Though, it's one-sided for Miyano. Not shoujo though.

Ai Yori Aoshi - Between Aoi, Kaoru, and Tina. All 3 super likeable. Not shoujo though.

Ao haru Ride - All 3 were pretty likable.

Thank you! Haven't started reading 360° Material yet, so I can't comment if it's what I'm looking for.

Already read Ao Haru Ride, but other guy has not appeared yet (I think) so I'll keep reading.

I'll give the other ones a shot as well, despite them not being shoujo. Thanks for the recs!
