(Bad) Orenchi no Furo Jijo

Series in one sentence:  
A teenage boy and a feminine merman with the mentality of an onion have an unsubtle crush on each other.

Series in more sentences:
A boy finds a weakened merman in need and decides to have him rest in his bathtub, but his guest is quick to grow accustomed to the pampering he receives and feels no urgency to go back home. Other mythical water creatures soon find out about the "luxurious" bathroom, but the boy shows hospitality and golden patience for these weird creatures and their behaviour.
 

That something this short managed to waste my time. Every episode is only 3-4 minutes long, of which half a minute is devoted to the overly edgy intro bit. Why they animated that for a show this silly, I'll never know.

But I figured the short running time would make it easier to check this thing out and hopefully find myself entertained, so I sat through every episode, no matter how bored I was.
Because there's so little time available to tell a decent story, there is no decent story. Every episode covers a random topic; it was the kind of nonsense you'd find in a children's cartoon, but with an abundance of homoerotic vibes.

I think the series would've been better if it was an actual series, not a series of shorts. You don't understand why the relationship between these men is what it is, as nothing of substance happens in these episodes.
The humor isn't especially funny, none of the scenes were charming, it's like this anime portrayed a basic idea for an anime, but didn't bother to take it seriously. A bit of a shame.
