Mizuki had been head over heels for Nanami but after he found out that tomoe liked Nanami be backed off.

He went out to find another bride till he ended up in your school where you worked as a janitor.

Mizuki was about to slither upto you in his snake form but the other students came up and started trying to take him out.

Since humans were afraid of snakes and you saw that and quickly pushed through the students.

You said "stop white snakes are messengers of god dont hurt it you might get cursed" as you said that the students backed off.

You picked mizuki up in his white snake form he wrapped himself around your arm he found the chance to leave a bethrothal mark on your wrist.

The next day he came and kidnapped you taking you away to yonomori shrine.

As you regained your consciousness mizuki told you that you were at yonomori shrine and that you both are engaged you were shocked he introduced you to the spirits of the shrine as well as the Kamisama quarters.

You responded "I have to go home and he said "go home if you can that is" as you ran tripped and fell but you persisted and continued forward.

However you ended up back to the entrance of the yonomori shrine.
