Slender:

He is very serious about somethings but most of the time when he's around you he's very relaxed and open about things you and him loved nature, you and him would either stay out in the forest reading or you would invite him to your house, luckily it was big enough for him to fit comfortably in the house he secretly had a crush on you (Well duh this is a boyfriend book) he would write poem for you and would read them out loud

Offender:

He was pretty chill he would do some flirty jokes from time to time you and him would chill at the park and maybe a little play fighting, you were sometimes stubborn (sorry if spelt that wrong) but he loved that about you he found it cute, you would invite him to your house and y'all would watch movies he  would listen to you rant and he would give you advice

Trender:

Trender was very sassy but you would always laugh and giggles at his sassy moments, he always made you the best outfits for any occasion even if it was just plain PJs, you and him would go to the art and fabric store and would look, you and him would always go to a small little cafe and talk about fashion senses you guys were pretty much best friends

Splendor:

You and Splendor would always go to parties, you would host parties at your house even if it was just a plain movie night or sleepover, you guys would go to any social event your city had you guys would go to carnivals and fairs, you guys would eat candy and sweets, you 2 would play games or just hang out in the forest, and you 2 would buy gift for each other, you 2 were the greatest friends
