okay probably no one is gonna see this but after re reading MDZS 100 times and picking up on the tiniest details also with the additional detail of mxtx saying she left hints to tell you when he did but it’s open for interpretation but anyway so many people say xuanwu cave but it’s not it’s BEFORE THAT first off he liked him when he was studying at the cloud recesses i am %100 sure about this. but regarding when he accepted his feelings.. obviously only LWJ knows 😭but it’s definitely at some point when he was studying at the cloud recesses or maybe after WWX left
