Tweet 1: [Sad News] The change of clothing my parents brought to the hospital for me is a double-V O-face Pretty Cure T-shirt.
Tweet 2: I was embarrassed enough already when I got transported there in a Homura-chan T-shirt...
Tweet 3: This is all the work of that jerk Torayarou.
(I can only guess he means this Pixiv user. The shirt, which says "Sweet Milkshake Torayarou" on it, is from Corpo-san's circle, but it may refer to the other user.)
Tweet 2 is referring to Hitori himself, he was taken to the hospital while he was wearing a Homura t-shirt. (post #2321553)
I'm aware of that, though I can see that the initial phrasing I chose looks a bit ambiguous. I'll tweak it.
