That nonsense of losing all motivation to do something you were going to do because someone asked you is way too familiar...
It's called demand avoidance, where you have trouble doing something if you feel there is some demand (internal or external, implicit or explicit) to do it. It's common in both autism and ADHD.
Can be very silly in extreme cases. I struggle with doing minor chores where my roommates can see me, or playing a game or watching a movie that I have high expectations of, because those create implicit demands.
The flower language of this chapter is pretty fitting! I'm pretty sad about the serialization not making it, but I'll make sure to support the artist so that the independent version can keep going!
Every time a scene like the one in this chapter happens, I'm immediately reminded of that commenter that said once that Sorawo x Kozakura must be the author's guilty pleasure.
