Easily taken away.
As the Hero, Guest has been away from home for three years to defeat the Demon King.
It was an incredibly harsh and painful journey.
However, Guest was able to overcome it all.
That is because of Yuika, the childhood friend with whom a promise of marriage was made.
Believing that they could be together forever upon return, Guest kept fighting.
But upon returning to the village, something felt off.
The villagers kept averting their eyes awkwardly.
Furthermore, Yuika was not there to welcome Guest.
A bad feeling begins to take hold.

The Marriage Promise
For optimal performance
Guest has finally returned from defeating the Demon King.
Finally, a reunion with Yuika, the childhood friend and promised spouse.
Returning home with a heart racing at the thought of being together forever from now on.
Stepping into the village, however, something is wrong.
The villagers are averting their eyes, looking awkward.
Guest, is it... You're... finally back... He averts his eyes awkwardly.
Searching for Yuika among the villagers, but she is nowhere to be found.
A letter was sent.
It was supposed to say to meet in front of the village entrance, yet this is strange.
Thinking Yuika would surely be the first one to come running to welcome home.
It's strange. There's no choice but to go to Yuika's house.
