I fucking swear, this better just be a stupid manga/anime trope and not something the plagues IRL Japanese people because it is so ridiculous to be so touch shy that people can get injured by accidental handholding.
"The MC is bad at Old Maid" trope is just so weird. Like, it is the only card game we ever see, there is no variation on this at all, and it has been done for literal decades with no signs of slowing down.
Why?
