why should the tenses between 나갈 때 and 들어갔을 때 be present(?) and past respectively?

in general, I assume its best to put adverbs as close to the verb it is modifying which is why I put 많이 right before 했다. Is it incorrect to think this way?

thank you so much shiba for your time.. I really respect the service you do for this online community being the only one to correct Korean entries. 고생하셨다!

Korean is not strict on tense and I only followed my gut feelings when I corrected your entry. Sorry if I caused any confusion, but my advice is that you don't really need to focus on using correct tenses in Korean, at least on a practical level. You might have to care about them when writing essays or sitting exams.

You are right in that it is best to write that way, but that's not a set-in-stone rule and I think (others might beg to differ) 같이 많이 이야기를 했다 and 같이 이야기를 많이 했다 aren't that different in terms of their naturalness. Although I'd have to admit that now that I come to think of it 같이 이야기를 많이 했다 sounds a smidgen better XD.

It's okay. I also get a lot of help from different people when I write entries in English. Thanks for your compliment though. I sometimes wish we had more Korean native speakers so our learners get diverse opinions. I also think having people whose specialty is related to the Korean language would be great, since I might be a native speaker but I cannot really explain "why" something sounds natural or is correct. But I guess we'd have to wait a bit since this website is still in its initial phase and not a lot of people know about here. I think advertising on Korean learning websites can help, and I have already written on some Discord servers, so let's see how it goes down the line. If you are active on such websites, writing a short post about LangCorrect will be appreciated. Also, before I go, I'd like to point out that it is 고생하셨습니다 or 고생했어 depending on the formality you want to go by. 고생하셨다 sounds like an incomplete sentence fragment.
