A compilation of stuff about Milk Tea i failed to mention on his Toyhouse, and am currently too lazy to add in.
(Some of these come from twitter!)
-Milk Tea wheeze-laughs. As in, when he laughs it's 90% wheezing. This applies to both versions of him and people tend to find it concerning
-When null he's immune to Pom's mirror, as he can't tie things like regret, shame, and/or trauma to memories
-He's very flustered by affection of any kind but especially romantic. He's not used to receiving it or experiencing emotions for it. More intimate affections like making out don't yield results that are as effective though
-The one treat he allows himself to have is a cup of earl grey milk tea when he has the time to make it. Earl grey milk tea makes him really happy when he has it, since it's what he's made of, so giving it to him will immediately have you on his actual good side
