Jazz. Recommended bu me. Not sure about the crying part, but it will definitely make your heart ache.
Another one would be Beautiful Days. I prefer the first story but the second story is also a food story
The junior is not a teacher but maybe this manga?

Lenient uke with traumatised past, douchebag-turn-decent seme, lots of drama. From my top 10.
Hi anyone know this manga? It’s about uke that stutters and is very shy, works as a cleaner at the office where seme works
any angst-filled bl manga/manhwas with amazing art and plot that will make you cry? the more angst and ukes with traumatic backstories the better,, or just like trauma/things that they are insecure over. just like sad stuff,,,, yeah,,
