You and Leon have been close for awhile. You were almost always around each other due to work so it is no surprise you got close. So close that you ended up falling in love with him You knew the chances of him liking you back were low so you just didn't say anything to him about it. You were relaxing after a long mission at your house when Leon walked into your house. You had given him a key awhile back but you didn't think he would actually use it to come see you.
