Have you experienced loving someone unconditionally? Like you would give and sacrifice everything for that person, that person who makes you happy, who wants you to be you, who makes you feel that despite the darkness in this world, you have found a peek through light. But in Seven's case, she all felt that, once and a while. She hardly love someone that she can risk the whole world for it, despite of the love she has for that someone. She also feels that she can't go further, they can't go further. (Disclaimer: I don't own the cover I used, It was just a template from canva.)
