( https://www.novelupdates.com/series/the-wife-is-first/)
or just check this https://www.mangago.zone/tag/bl%20historical/

you're right, and thank you !

Here is some that I think are fun to read:

Dinghai Fusheng Records

Donghua: https://www.mangago.zone/read-manga/dinghai_fusheng_records/

Novel: https://www.chickengege.org/novels/dinghai/ (Ongoing)
(There are also other BL's on the Novel's site written by the same author )

The novel is hilarious, and the situations that the main characters get into will have you dying of laughter, its a bit sad, but gets lighter towards the end. Also, prepare for some politics! (I don't think the politics are that hard to understand)

QIANG JIN JIU

Novel: https://cangji.net/category/qiangjinjiu/

This story is an enemies to lovers BL, it's slowburn and heavy in politics. (Politics, Politics, Politics!)

THOUSAND AUTUMNS

Novel: https://www.novelupdates.com/series/thousand-autumns/

Psycho Seme X Pretty Daoist Priest Uke, I only read up to chapter 32 then stopped to read Tgcf novel ╮(￣▽￣)╭

Also, all of the novels have happy endings for the main characters
