my thoughts...
Truthfully in a way I liked that there's no 'happy' ending, it's somewhat realistic as Lillian's relationship with the boys is kinda purely lustful, in that yeah they have chemistry, but the life or death situation of being a spy simply heightens the feeling. Also thinking about it was hinted with Emile saying 'being in love is different from being involved'. In a way, it reminded me of 'la la land'.
BUT I actually somewhat wish we got an epilogue as the endings felt quite abrupt, and I didn't feel satisfied.
I feel for the price we should have gotten more content, as compared to other games e.g. Red Embrace Hollywood, and Bandcamp Boyfriend. There's a lot more content there and in a way, they're better written.
