Zach was so happy looking at the weapon description that he unconsciously pulled Diana into his embrace and kissed her forehead with enough force to penetrate into her head. His joy was untamable like a bull that successfully managed to break out of a fighting arena.
Diana couldn't understand what was happening. One moment she was talking to Clara and listening to her words of thanks and the next moment she was in Zach's embrace being showered with kisses that felt like bullets striking the base of her head. Despite the sudden invasion of her privacy, she didn't feel anything but happiness from Zach's actions. Her whole face turned crimson as she tried to remove the dirty thoughts that popped up into her head one by one without relenting.
The crimson hue on her skin made her ephemeral beauty escape the confines of mortal chains and helped it ascend towards godhood because only gods had the right to look so enchanting and unapproachable at the same time.
