Hahaha I also loved these types of BL
I'm not sure if I understood your "deep connection" requirement correctly but here's something I think you might like.

Highly recommend this one if you haven't read it already. Probably one of the best omegaverses out there. I absolutely looove the second pairing way more than the first lol.

This one's new. Nothing says deep connection more than reincarnated lovers meeting again but have no memories of their past. Omegaverse. http://www.mangago.zone/read-manga/keeper_of_the_pearl/
