I'm looking for romance manga recommendations that involve interspecies love where the non-human doesn't look human but without harems and smut. Thank you.

Man I've been searching for that kind of thing for years. Good luck in finding many (good ones anyway) without the human looking part.

H-stuff:

Pretty Lamia (top half human)
Jingai Haruman

edit: apparently spoil tagging doesn't hide links...

You could also use advanced search with the Human-Nonhuman Relationship tag though I know how futile that is. Might need to start adding a nonhuman appearance category tag to stuff... Would definitely help. If you find any more let me know, would appreciate it.

Sorry im too lazy giving the link lol here's some
Kumika no mikaku (human-like alien)
Boku no tsuma wa kanjo ga nai (android)

Both are human-like tho
