Blood type A

The Planner

Careful, considerate, quietly holding everything together.

In Korean and Japanese pop culture, type A is the organized one: the friend who books the restaurant, double-checks the train time and notices when someone in the group has gone quiet. The stereotype is of a person who cares a lot about getting things right and about how others feel, sometimes at the expense of their own ease.

Type A in love

Type A is said to fall slowly and stay steadily. They show affection through small, consistent acts: remembering your coffee order, checking you got home. They need reassurance more than grand gestures, and a partner who is casual about plans can make them anxious without meaning to.

Type A at work

The classic type A colleague is the one everyone trusts with the spreadsheet. They thrive with clear expectations and do their best work when they have time to prepare. Last-minute chaos is their least favourite environment.

Type A in Korea and Japan

In Japan, where type A is the most common group (about 4 in 10 people), the A image is close to the cultural ideal of diligence and harmony. In Korea, A is also the largest group, and the stereotype of the "timid but kind" A-type person shows up in variety shows and webtoons.
