I recently joined a guild on an Asian server, where the leader sends me a daily dm like “今日もよろしくお願いします！” When I’m online at the same time, I do reply with something like “こちらこそ、よろしくお願いします” (though I’m not fully sure if I’m using it right). Most of the time, however, the leader sends it in the morning Japan time, and I usually log in much later (around 1–2am JST, which is already the next day in Japan). By the time I see the message, they’re often already offline or about to log off. If I reply at that point, it feels a little weird timing-wise, and if I send the same greeting every day it also starts to feel a bit stiff. Also, they usually say in guild chat when they’re about to log off, so I might do a quick goodbye there but not reply to the dm. Because I keep overthinking this, I often end up not replying to the dm, and I haven't replied to the leader for several days now,and if I keep not replying, it starts to feel a bit impolite — so, what’s the best way to reply or handle it?
