小春と湊 わたしのパートナーは女の子

A cute and fluffy set of autobiographical episodes of a formerly long-distance couple with a 10 year age gap (20 & 30) living together. Perfect if you just want your dose of hyper sweet yuri content.

However, the volume doesn't make much use of its premise - particularly the age gap goes entirely unexplored, until the final chapter (I would actually recommend starting with this chapter, and then reading the rest of it). There are no side characters, and no dramatic tension - just Koharu and Minato being over the top in love with each other. It's entirely episodic, so you can sort of just pick up and leave off wherever. While Koharu and Minato are both sweet, they don't get much in the way of characterization, so it's hard to feel too excited reading it.

While I usually read my manga straight through, I think this may best enjoyed a chapter or two at a time. The main reason I'm reading it is because it's serialized in 百合姫 every month, and it's a relatively light read.

If you're looking for something with an established couple and some more depth and tension, that balances episodic and linear story, I'd recommend はなにあらし | L18 (though it is a high school story).
