When new mode came out looked liked liek it will take forever to max chats so i bought 2x replies to have 8. Mistake obviously lol. I have 50 girls used 300k affection on them(so you know that i have most of them lvled up a lot) and all their chats maxxed. It was quite common 1 replies cleared 2 sometimes even 3 slots. So i am a bit dissapointed buying more replies so dont do same mistake :)
