Tsukasa was a knight in a kingdom where there was a king who had a son and was a prince. his name was Rui. the boy didn't like royal life, so he often sneaked out of the kingdom with Tsukasa.

they were just walking along the river. Rui looked a little tired.

"would you like to rest for a while, Rui? you look tired." Tsukasa said with a calm voice as he gently wrapped his arms around Rui's shoulders.
