Wsp!! I'm qiao, similar age and roleplaying experience as you.

I'm interested in your teacher x teacher idea first and foremost, but I can totally see fitting some of your other ideas in there. For example, an enthusiastic, optimistic new hire is introduced to an older, disillusioned mentor. This can take place in the late 90's, a time where the prevalent feelings are hope for the new century but also fear for what the future will bring, creating a direct parallel with the characters' personalities. There can also be a bit of drama regarding the social taboo of being gay in such a setting and I think it'd be interesting to see how our characters navigate that. If you want to discuss further into this, do reach out.

As for what I have to offer just so you're more convinced, I
- have been roleplaying for nearly a decade (whether I am good at it or not remains to be seen)
- can do faceclaims for my characters, but they'll all be shitty scans of sketchbook drawings until I get my tablet fixed
- am alright with most mature themes (only exception I can think of is if you get off to like. snuff, that's kinda weird,)
- can communicate daily even if I don't update daily. I try to update from every few hours- 3 days at most and will let you know if life gets in the way. 
- am open to criticism (including rewrites if you don't know what I'm saying lol)

And lastly, what I want:
- good communication from you too; lmk what you're uncomfortable with if it comes up, what you'd like to see, etc.
- a wholesome story? I don't mean that nothing serious or bad happens to these characters, just that they experience genuine growth and have heartwarming moments with each other regardless of the outcome of the story itself
- understands basic english (will not be incomprehensible) (good news I understood your post so you pass this with flying colors !!)
- general vibes of silliness and whimsy (I am half joking here; you don't have to be a clown but also don't take yourself too seriously you know)

Anyway I mentioned this before but hmu if you think we're a good fit! Looking forward to it.
