Shiroi Goshiki from A Galaxy Next Door.

She's the assistant of Ichiro Kuga, who is a manga artist. The first time i was reading it, I thought it's going to be one of those manga's where the FMC is a tsundere and treats MC like crap but I am glad it wasn't so. She's a kind and very gentle girl but she easily gets embarrassed when talking or having romantic experiences with Ichiro. Started watching the anime after finishing reading the manga and it's just wholesome. Totally recommend it. The manga left me wanting more of Ichiro and Shiori's happy life
