I devised this 'SEAF' framework for myself. 


’SEAF’ framework contains Jobs To Be Done & User Journey, 

which allows effective & productive UX design in the agile build-up process.

A few feelings from users are closely associated with 'WHY'.
'WHY' denotes why users felt that way
'WHY' is not a result but an underlying purpose, cause, and belief.
At the moment users feel uncomfortable using a product, I have to trace the feeling of how come that came up

Typical link-in-bio services underlie nothing more than a link button
to enable users to move to the original platform.
But the Whoami service paid attention to experiencing a private mood board.
Users can showcase their liking and personality info such as zodiac, MBTI.
