[Even Ritsuka's (human) ears are tinged pink after a comment like that.]
There's no way the robot could know something like that. [His heart is racing, and he can't stop blushing, and stupid Soubi can just stand there and kiss him again so casually - something swells in Ritsuka's heart, a feeling squeezed painfully into his small body that he neither wants nor understands - anger? affection? embarrassment? happiness? He feels almost like he's finished a spell battle, the invisible tightness of restraints long since vanished choking him, binding him, holding and hurting at the same time.
Maybe he is still a little frightened after all.
But it's hard for Ritsuka to ask Soubi to stay with him; it's hard for him to make demands because they sound too similar to orders instead of something he means from the bottom of his heart.]
If you have something else to do, I can go the rest of the way to the library by myself.
