I imagine Rukeewei would be feeling similarly to Ariel about it. They basically had an argument that started with Rukeewei neutrally asking why Ariel doesn't have much free time, then asking if she might take some more time off so they could hang out. Ariel is pretty passionate about her work and was tired at the time, so she misinterpreted and thought Rukeewei wanted her to give up her shop. This caused her to retaliate by calling the Wamasu's nest a smelly pit of a place, which set off Rukeewei to say something similarly rash about Montgrave Remedies. They've had some time to get over it, but it has just been a matter of one person approaching the other about it.
