Please recommend any other similar manhwa you know, or any poly/throuple BL

I became a first-class guide thanks to my childhood friends

The Shape Of Us (Yaoi) is really good
(BUT it can be frustrating because of lack of communication but imo it does a good job not romanticizing poly relationships like the characters actually get jealous and work things out it's not just rainbows and sunshine every day the characters have character development)

If you find anything else please let me know, we don't have a lot of poly stories

Help Me, Teacher

Can angels do this?

Guiding hazard. No throuple but bad ex
