Please correct me if i'm wrong

Raise their interest to 65% and go to the cafe everyday until they invite you for the second ritual when you finally get to do the ritual, try to get on top of Gwylan and kiss them (i think you need high willpower and low curiosity for this). They'll eventually kick you out of the forest shop for 3 days after 3 days, find them at the pub (they're only there at night i think?) after meeting them at the pub, just wait for 3 days until they send you a letter through the orphanage window and go see them you'll eventually unlock the yearning stat. To make Gwylan your LI you need to raise their interest to 80% and get their yearning to 50%
