Their names are giving me a headache

Yessss I already gave up reading and remembering those names (づ￣ ³￣)づ

Haha yea, i was hoping they would give each other short nicknames like asty for the twin brother and lea for the female lead
╮(￣▽￣)╭

Edit whoops my bad seems like the female lead was given the nickname lea but i dont recall the same thing happening for the other characters, either way, the names are just a jumble of letters for me at this point
