Yishin’s master is Suyeon (mc) from the future, she probably married the blond guy and is unhappy, so when she’s meeting her friend she says smth like “it would be nice if we met earlier”, so she sends Yishin on a mission to either kill Suyeon or not, in which if he doesnt he stays there, so the master knows Yishin cant kill Suyeon, so he’ll stay there with the mc. And the main reason for the mission to be about killing is, if it was smth more simple and easier, he would want to come back to his master bc he likes her. So the master is probably changing her future by making past her fall in love with Yishin. Just my thought though
