would (just) as soon idiom (also old-fashioned would sooner)
C2 宁可,宁愿
If you would (just) as soon do something or would sooner do something, you would prefer to do it rather than something else that is possible.
"Would you like to go out for dinner?" "I'd just as soon stay in - I'm not feeling very well." “出去吃饭怎么样?”“我宁愿呆在家里——我有些不舒服。”
I would sooner have you hate me for telling you the truth than adore me for telling you lies.
