The Lover (2015)

Both dramas:
- tell stories of neighbours, in reply they know each other since kids and in the other are couples who live in the same building
- are hilarious
- have cute romance
- have the same vibe
- that dialogs owo
- every character is important and have its own story
(bonus: in the lover you have bl)

These dramas are very similar in that they both revolve around the stories of couples in the same building. They both also include a gay couple. However, Tonari no Kazoku wa Aoku Mieru does not have much of a comedy elements.
