I would suggest you reread :) Not because I think you don't understand or something like that, but because I have reread it multiple times and you get more invested in the story and understand a lot more every time around. I must've reread like 6 times by now, hahah. It's something I recommend for everyone, really; it's different from waiting and reading a new chapter every week.
Haha, I can totally relate. I've always been bad with names but after reading >150 chapters one would think I could at least remember three names... but noo, it's the blond one, the blond one's (soon to be boy-)friend, the dark one and the redhead. Bummer since I've only read the comments in order to find out what just happend with the letter :D
It's sad how I still don't know what any of their names are. I know there's long haired guy, long haired guy's love interest, black haired guy, and then gangster dude...
