I am looking for a manga a read a while back.

There are multiple couples in one manga.

The first on are two friends that attend the same school and one found a dog and gave it to the other.
The next couple is one of the boys uncle(detective) who he had to move in with but he is in a relationship with the neighbor.
Lastly is the detective partner who is in a relationship with the younger sister friend. The family consist of firemen and the detective.

I hope this is enough. Please Help me!!!!! 🙂

More likely to find what you are looking for if you post topics like this is the Yaoi/Yuri section 😃
