it's right here https://www.mangago.me/read-manga/happy_together_paradise_scans/
to answer the first part of your question: if the title has been changed sometimes it can seem like a story is gone when it's actually not, it's just been renamed and sometimes the site wont register when you search with an ALT name
Ohhhh, that's why. Noted on this, been worried because I can't find it when I was about to read it. Thank you for answering and for the link.
What is the reason some manga/manhua/manhwa are missing in this site? I just notice Happy Twogether is not here anymore.
