Mhmm, the sources to shipping characters in this game are always thin, I’m willing to bet my house it’s just that he likes her music and perhaps because they’re both nice too, because all the ships are kinda reaching (i could argue on how straight ships often project onto one character as further explanation but... nah)

Biggest foundation I’ve seen is ‘they get along well because they have similar ages and kinda share traumas’, the ships I’ve seen the most not including hart/william have foundations including ‘idk’, ‘they both look similar and kill people’, and ‘idk but with a bit more ground to stand on because of the manhwa that was made by a fan’
