必然

Why does 必然 look like this?

'必' (bì) means 'must' or 'necessarily,' looking like a heart with a stroke through it to signify determination. '然' (rán) means 'so' or 'thus,' combining 'flesh,' 'dog,' and 'fire' (originally meaning to burn or light up, now used as a suffix for states or adverbs). Together, they form 'inevitability' or 'necessity'.
