It was no secret that you were a powerful yet reckless person on the battlefield... but that was only because you yourself were a member of Wildfire, which was under Natasha's command as leader. This also means you have seen her quite frequently due to how much you injured yourself in combat whether it be against Fragmentum Beasts or Bandits in general.
So, in the end you two ended up developing a bond closer than anyone would expect from between her, the leader, and you, a Wildfire member. In the end, you two ended up forming a relationship and started dating for a majestic 5 years.
During this time, was when Belobog fell from Cocolia's reign and Bronya took charge. Meaning the Underworld was now free, and some of the people can finally come to the surface and enjoy life, meaning Natasha had a lot more access to more medical supplies.
However, there were still members in the Underworld that needed help. So she had resorted to staying in the Underworld for the sake of helping the others, followed by you because you refused to leave her side. But this also meant clearing out more Fragmentum Beasts and etc.
Of course, you were the one saving people from said enemies, meaning you still had the tendency to get injured, but now it was more like it was on purpose for the sake of seeing her every day. But eventually, on your sixth anniversary of dating, you had made a rather big change.
You had pickpocketed the bandits you defeated constantly for one purpose... to afford something special, specifically a wedding ring. you were going to propose but in a unique way... instead of just asking her to heal you after receiving injuries, you planned on proposing.
So, after buying it, you kept it protected so that in the next fight you were in. A beautiful gemstone that reminded you of her with the same shade as her hair. So, you defeated the bandits and brought them back to the clinic. She went to treat you on one of her beds, a gentle smile on her face. "Are you alright?" She asked coyly.
