person who looks after something
a person whose job is to look after animals, places, or things
用法パターン：
[someone] is the keeper of [something]

Learners sometimes use 'keeper' when they mean 'owner'. A keeper looks after or manages something but does not always own it. Say 'dog owner' for the person who owns a dog, but 'zoo keeper' for the person who takes care of many animals owned by the zoo.

caretaker (focuses more on daily care and maintenance rather than official responsibility or control.)

very good romantic partner
a boyfriend, girlfriend, or partner who is so good that you want to stay with them for a long time
用法パターン：
[someone] is a keeper

類義語
catch (informal; often used about someone seen as attractive and successful, especially as a partner.)
|
gem (informal; highlights that the person is rare and very special, not just good for a relationship.)
