I have been wondering for a while but is the homeroom teacher that died the MC's sister or...

I'm fairly sure it's his sister

I was sure too but someone said that the minister and mc have different surenames and she could potentially be his lover

......they have different surnames??? Also he called him his son and they mourned for her as the minister's child and the mc's sister at that grave scene

I asked the same thing but that person said that he.might be calling the minister his father cause he made a deep conection when his lover died. Well idk i would like it if she was her sister cause the red head might potentially be the FL!

That's what I'm hoping too lol

Minister and MC have different surnames. MC could be minister's son in law (hence, "dad") and u can also mourn ur dead partner because they are still family.
