？？？「こんな時間に女性が訪ねてくる。……かかったな、泥棒猫が。」

ライトハローさんはただライブの話とかをしに来ただけできっと無実。
しかしトレーナーが女性と遊ぶことを担当ウマ娘に話を通しておかないのはマナー違反。きちんと事前に伝えておき、遊んでいる最中も定期的に連絡を入れましょう。

……
え、ん？必要か？担当ウマ娘にそんなこと伝える必要あるか？ないだろう？ないな。
そもそもなんで夜に当たり前のように担当ウマ娘がトレーナーの家にいるんだ？
掃除？掃除か！掃除なら仕方ないな！！

"What kind of woman would come waltzing along at this hour? ... A thieving cat, come for its prize, perhaps."

Light Hello-san is probably just innocently wanting to talk about live performances.

However, the Trainer should know better than to keep the lady in charge in the dark about women coming over. Let her know in advance and keep in touch regularly when you are socialising.

...

Huh, really? Is it necessary? Is it really necessary to to let the Horsegirl in charge of the house know? It isn't, right? Of course not.

In the first place, why is the horse girl in charge at the trainer's house at night?

Cleaning? Cleaning, right! She can't help it if things are so messy!!
