Did you play an older version of the game or is it your first time playing? In the second case, the main menu disapear only if you select "I play on a computer" instead of "I play on android device" when Emilie ask for and then you say "No" when she ask if you want the quick menu... If you selected "I play on an android device" at teh first question, there is no reason for it to disappear.
Thank you for yoru message, really happy that you liked the game so much!
For your question, it's intentional. Even in the love path, the MC is still a dominant person and this is something that Emilie appreciates even if it is less visible than in the sub route. Emilie's reaction at this point depends on the interaction the MC had with Jenna (if he kissed her or groped her), and Emilie will push a bit in the direction the MC wants for this relationship
