just move <b> from data value direct to the template
<template>
<div>
<v-textarea style="font-weight:bold" v-model="value"></v-textarea>
<p><b>{{value}}</b></p>
</div>
</template>
</div>
</template>
<script>
export default {
data() {
return {
value: "This is the value",
};
},
};
</script>
and then configure textarea with css to be bold
