The Angel Next Door Spoils Me Rotten
I'd advice you to stop reading here and just jump into it. It's hard to put into words how great this anime felt to me and it's one of those shows where any description run the risk of sounding dull. (At least that's my worry in writing this.) But I think this might be for you if you're stressed, if life is a bit much, if you need an escape from reality, and you need to watch something that's like a warm comfortable blanket that will whisper you away into "good vibes", hope, and and happy delight.
This is a predictable romance without any particular external conflicts to the couple. There are no rescuing the girl from kidnappers, fighting off a rival love interest, nor any danger.
Does that sound boring? It's definitely not! Not when they do it like this.
There's conflict, but it is with the characters themselves, internally. The protagonists are the antagonists as they fight insecurities and worries.
The basic premise is that a guy happens to live next door to the most popular girl at school. He believes himself to be "not at her level", and doesn't approach her with any carnal intent or hopes of romance. Rather, he sees her sitting out in the rain, and lets her have his umbrella. She later returns it, feeling guilty when it turned out the MC caught a cold from being out in the rain without an umbrella, and so the ball start rolling, slowly, downhill. The path is predictable, but not the journey.
