One Room, Hiatari Futsuu, Tenshi-tsuki.

The main character Towa is very similar to Mahiru Shiina - always cooks, cleans and most importantly waits for the main character at home + the main character himself is very kind and responsive, always tries to help the main character herself and hide from others that he lives with a kind and beautiful girl the only difference between this anime and the anime Tonari no Tenshi-sama ni Itsunomanika Dame Ningen ni Sareteita Ken, this the supernatural genre, however, it does not interfere with the viewing itself and leaves a strange pleasant impression. 

“Ya Boy Kongming!” is a comedic and fantastical series where the ancient Chinese strategist Zhuge Liang (Kongming) is reincarnated in modern Tokyo and uses his tactical genius to help a young singer succeed in the music industry. It combines historical elements with contemporary life, highlighting the humorous clash between past wisdom and present-day challenges. On the other hand, “One Room: Hiatari Futsuu” is a first-person perspective anime that focuses on intimate, slice-of-life interactions between the viewer and various female characters. Set within the confines of a one-room apartment, it offers a more personal and immersive experience, emphasizing character development and everyday moments. While both series involve personal interactions in limited settings, “Ya Boy Kongming!” emphasizes comedy and historical fantasy, whereas “One Room: Hiatari Futsuu” provides a more grounded and intimate slice-of-life experience. read more 

Both series are about relatively normal people having their lives turned upside down when a mythical being starts living with them. 

IDK, but Renai Flops just yelled back in my mind when I started watching One Room. The animation is similar and the initial good vibes really resonated with me. Just know that you can be kinda emotionally devasted by the end of Renai Flops but I think the ride is Worthy either way. The girls are cute and the protags aren't duchbags. Feels right in my book. 

Tired,? Have been working for hours relentless and just want to chill? What about chilling with a Angel (One room) or a tiny fox lady (Senko-san)? Make your pick and whichever choose is guaranteed to bring comfy and warm feelings- just when you know that someone cares for you. 

Angels that fell from the sky and start to live with the MC. They show their way to each other and get to know each other... they bond together and learn about each other. Sora no Otoshimono is more cheeky than One Room but an absolute gem as well (the protag is a hell of a perv but has a good heart). One room have a cinnamon roll of a protag. I just love the angelical vibe of each anime (btw Sora no Otoshimono have a good and interesting lore). 

Monsters/creatures from folklore around the world living between normal humans in humanoid forms. In demi chan, you see the "half" creatures of these popular stories - consequence from the union of a normal human and a mystic creature. In the series there are all "monster girls" if unique issues that they have to cope with to blend with society. The protagonist of both shows follow and of the characters mystic ordeals. 

A Angel (One Room) and a Goddess (Ah! Megami-sama) comes to the "normal world" and starts to live with the protag. Ah! Megami sama has a university ambience and One Room a High School one. The Angel/Goddess and the protag, in both works, get to know each other and starts to live together. The Angel/Goddess get to know the human world, bonding with the protag.
