As someone who never watch the anime but has read the VN, the manga is great. They portrayed Touya and Yuki having more of a bond here than in the VN. They also go a lot more in dept for Haruka compare to the VN where she is distant for a majority of the time. The manga botch Mana relationship with her parents as it not given a clear reason why she hated her parents. Making here more of an immature sidekick to Touya. You see how Touya got his jobs instead of it being given to him in the VN. Eiji is more likable here rather than an imposing creep, which is a good change imo. It is a good adaptation to a dated but still solid VN. 9/10. Extra point for the expressive art style and fanservice
