Literally just imagine being Yukari in this picture. You're a youkai that's thousands of years old, respected and feared by almost anyone. Very few people will approach you, because those who don't know you can sense something off, and those who do either view you as an enemy or are terrified of you. Much of the scheming behind the scenes in Gensokyo is done by you, with all that entails. Yet, for the first time in your life, you get to feel secure in someone else's arms. You may be powerful, and some might even call you a monster, yet none of that matters now. Your powers may as well not exist, because for once, your sense of safety comes from someone else, not your strength. As they tell you they'll keep you safe, you know they really mean it. You can trust them and let them lovingly hold you in their arms, caring for nothing else besides them. Despite what everything else thinks, and despite your own high opinion of yourself, deep down you know that all you really want is for this to last forever.
