[This section is in the POV of Leo and Walker]
When they first arrived at their table, Walker naturally sat at the very end, by the window, while secretly motioning for Leo to sit next to him. Due to this arrangement, Hunter and Gray had no choice but to sit opposite of both of them. After all, Gray was quite reluctant to let Hunter to sit across from Walker and let them interact again.
Walker had originally forced Gray to go have dinner with him, since Gray had promised that he would go on a date with him earlier. Since he knew that the relationship between them was still quite cold, they shouldn't spend too much time together, as it would simply annoy Gray instead of fostering intimacy.
