If you leave her to fend for herself in the mall, the relationship with her is essentially over. Or were you able to continue with her afterwards (between day 34 and 139)?
exactly that's the bug,i follow walkthrough so knew exactly to follow her to continue our relationship but regardless of what we choose,bug takes in code as if we let her wander and left her in mall,so the scene in cafe where we invite her or continue our relationship is not there.i guess it's a simple big in code where that choice to follow her or not is taken by codes as not,no matter what we(players) choose.
actually I deleted game after the harem ending but wanted to report the bug,and about her relationship status,i don't about other devices bit for me only MCs sisters and mother relationship and pregnancy status is shown not of Riley but bug is at that particular mall event only,where our choice is not considered due to big.and we will broke no matter what we choose the event to meet her in future in cafe will never occur.
