a female came down from space and the the male protagonist
romance in both anime

both have a boy protagonist who make film
both funny in its way
The Female MC from both series came from some other planet, they both fell in love with the MC, only difference is that One is actually romance with normal looking character and the other is FanServies with cat looking girl......
Both series have a shy male protagonist and a pretty alien girl who is protecting him and in love with him. Only Asobi ni Iku yo! has more action and Ano Natsu de Matteru is more slice of life.
Both of them are based about teen boy who is living their life and an unexpectedly an alien appears and is forced to live with them for one reason or another. These animes are about the difficulties and embarrassment that both these teenagers face and how they cope with them. There is a lot of comedy mixed in with lots of seriousness.
