Tsuritama, Sora no Method Recommendations
Both are slice of life comedy shows about a group of friends (boys in one, girls in the other) in a small town by the waterside. Both have a friendly alien in the group. Tsuritama is more comedic and is also about fishing, whereas Sora no Method is just about girls being cute.
They are both slice of life anime that include fantasy in its story and there's no romance directly misted in the story. they go through trials and over overcome it.
