I must have brain rot because I keep hoping there will be some side BL pairings. ╥﹏�...

I feel there are some lgbtq hinted.

The 2nd prince with his beast servant youbi.

Tenyou seems to be bisexual or pansexual. He was ready to be with rangetsu, even though he didnt know about her secret yet.
He is also attracted to songetsu and loves seeing the twins together. But maybe is because he loves rangetsu and songetsu has the same face as her.

I believe songetsu is also a Part of the alphabet. Which i'm not Sure. He is still healing from trauma.
