A Goodbye Promise is the 54th substory in Yakuza Kiwami. You need to meet Yui at JeweL and visit her to take Rank A. You need to take her out before reaching the Rank A! After that, you gonna receive a call/mail from her and you gonna get a substory mark at your map.
Don't buy expensive stuff or you never gonna make the Rank increase! Just buy Black Champagne and order the 2° and 3° foods.
