I had a surprisingly hard time thinking of an actual Weilan date - they behave like everything they do is basically a date already. I feel like they might try a bit of 'traditional' date stuff but eventually conclude that, really, it's not necessary to make such a fuss of hanging out, and scheduling is a pain in the ass when you're two very busy people with unpredictable schedules. Anyway, I think their first date would be a walk in the park so Shen Wei can enjoy the sun, and Shen Wei probably brings some food so it turns into an impromptu picnic eventually.
