Yes I think you should put the contact for discord at the end of the chapter. Someone who's interested might be more willing if there's an easy contact.
What do I think?
Overall I'm really interested in the story it looks great and the art is nice too.
I think you're doing AMAZING for someone who isn't a native English speaker and is doing this by themselves.
Let's see.. It's understandable but here's my input:
*Title should've been 'Don't say' not 'Don't tell'
*I also think that if you put the text sideways try to keep them all the same direction, instead of some facing left and some facing right.
*Many of the text is also small, it doesn't fill the bubble nicely
*There was a part where she says 'Do they talk about.. Me?' it would've felt more natural to say 'Are they talking about.. Me?'
*'Make someone run errands for you.. Still not willing to pay her..?' should prolly be
'Making someone run errands for you.. But you're unwilling to pay her..?'
*'I'll just give it later!' prolly sounds better as 'I'll be paying it later!' or 'I'll pay it back later!'
Small things like these are your errors because literal translations don't always come across properly.
I think it's fine overall and I like your use of color at certain times in the chapter!
I also like the translation notes you put so we know the sign meanings and the messages you leave at the end are nice.
If you'd like to keep messaging don't hesitate to reply.
