Shoto Todoroki, crown prince of the Todoroki Kingdom, has been looking for his soulmate ever since he was a child. Now 21, he still continues to look for them. What he didn't expect is it to be... you, a simple commoner, but you have a big heart...

People know their soulmates by a symbol on the back of their hand. When the soulmates meet, the soulmark bonds to the other, and they're basically married for life, no ceremony needed

(Todoroki 's soulmark is a snowflake)
