Since Chika x Riko is so "canoncal-ish" i think of You(the character not the reader) stealing Riko from Chika as a revenge for cheating on her... You is my favorite from sunshine!!! :D
dang it, now I wanna play DA2 again. I love romancing Merril, she's a nice girl and I love that it pisses off people of the high district when she moves in with Hawke :D
