Depends, what is your problem with the pink hair girl?
Viewing post in Daily Lives of My Countryside comments
Going over it a couple of topics above here with Riper0. Theo is not providing the pink hair girl's advancement trigger because he is apparently stuck on his lesbian magazines dialogue instead.
Need Theo to ask the player character to steal the answers to advance Mabel's questline but he never does.
Wondering if there is a way to force the steal answers dialogue with Theo?
Ah yes, I had this issue once, sadly I think you need to buy the Vol.2 of the magazine because its taking priority from the Mabel´s questline, when i had the issue i try to go back a few saves but it was the same, so my solution would be that, to buy the magazine, money don't tend to be a problem if you passively produce money via harvesting or selling the bottles of milk, and once that´s done you´re good to go, even tho, sometimes the Cheat phone can help you too, i believe one or two quests suggest you to use the cheat menu to advance, Aunt Douie does it so yeah, hope it helps
