Cute! but could only be an AU thing. Hadel thinks of himself as a "hard boy", I can't see him willingfully wearing them. He'd already be extremely embarrassed if anyone else knew how much Luca babies him as is.

Ludel in canon have like.. a similar...??? dynamic as like ABDL x Caretaker, but if instead of being age-regressed to a toddler-like mind, Hadel is age-regressed permanently as like a young teen-like mind... if that makes sense LMAO. Very ornery and needy and careless. Obviously wants a partner that treats him more like he's their son ..but with sex and kisses too.

After his trauma, he age-regresses further during episodes / psychotic breakdowns or catatonia, but its still not like an ABDL thing, he just needs cuddles, stuffies, a good animated kids movie, and extra careful pampering.

So ig like ABDL Hadel would not be.. too far fetched? Not my thing truly, but I'm not entirely against anything either pfft.
