As Cobalt sometimes aids her when she's in heat, satisfying a primal need, Mallow also assists him when he feels the pressing urges of sexual desire. When they become intimate, Mallow can often grow more wild and passionate, sometimes even overwhelming him with her intensity. They are still exploring each other's boundaries, experimenting and discovering what pleasure and sensation mean to them.
In the aftermath, Cobalt often feels a twinge of guilt. He longs for more than just sexual gratification and the mutual fulfillment of their physical desires. He wonders if Mallow wants the same, knowing how wild and independent she is. She's a free spirit, never needing company, even if she's gone for days or weeks on her own adventures. This leads Cobalt to doubt whether Mallow would even want a deeper relationship, and he's hesitant to ask or reveal his deeper feelings to her.
Though he's somewhat insecure, this insecurity stems from her unpredictable behavior. If he knew that Mallow loved him, he would be the happiest man in the world. Despite the seeming mismatch in their personalities, Cobalt is drawn to her wild, chaotic, and playful nature. And he adores that Mallow doesn't judge him by his appearance. She wants him, desires him, just as he is, and she isn't shy about letting him know. Her affirmations are more than words; they are shared through touch, taste, and shared pleasure, binding them in a connection that Cobalt hopes might grow into something more profound.
