There's something with me about names of people I crushed on or liked (inlcuding some bishies) where I felt compelled to be cryptic about it during the time (even to myself in private) so I'd have words or made up characters/names to stand in their place and be used in writing, conversation, and even art. It's almost superstitious in a sense, though I still don't know why I'm like that. I know it doesn't apply to my boyfriend because 1 - I'm in a relationship with him and 2 - it's a damn good relationship, unlike a past one where I felt the need to employ the cryptic name behavior.
But back on topic, yeah, if you count the words/names I used in their names' stead, I have most certainly written them on paper in cute or elaborately decorative fashions. Haven't done it with my boyfriend, though 'cause I'm more interested in drawing his character X3
