This is actually a really good manga. The love between the two siblings is being built up slowly, and it’s truly beautiful. It’s one of the rare incest series where the MC doesn’t fall for everyone and create a harem like in most others. The only person he can think about is his sister, even though he tries to date other girls with her help, no one else makes him feel anything or makes him happy. I really like that the author didn’t turn the manga into a harem and chose to focus solely on the love between the siblings
