You are talking about the request to escort hero to city. I was asking about request to join hero-party. I have a vague memory that mc was the first person hero requested join him (and was rejected because of mc).
It still aligns with that. Relix did asked Yukina to join with him to the capital (and in Yukina's way, he went along with it, being "babysitter" but also split from him mid-way upon arriving at the capital in ch.1 but met up again at the near-end of ch.2 and splitting up once more again on Relix's end for the sword)
After a series of stuff on Yukina's end and the different stuff on Relix's end, did they more or less happened to meet again 'face to face' right after Yukina defeated the kobold boss while saving Shikage/Mikage but Yukina passed out soon afterwards in ch.5
Then you got ch.7 with Relix alongside Aina there asking Shikage/Mikage to join Relix the Brave like in that same post I posted awhile ago in reply to another user (in regards to Princess Aina) which also more or less some bits on Hero and Brave and the slight similarity and difference they do (from "their respective weapons" too i.e Gram and Leiva), especially the stuff from ch.8 regarding Hero and Brave
Then you got ch.10 here with Relix more or less found some members for his Brave party while for Yukina it's just him and Shikage/Mikage, and throw in Kyunei into the fold as part of Yukina's group as you could see in this chapter.
Meanwhile, there's Princess Aina, but Relix currently has Mayuri as Aina's replacement as the mage for his group, because yeah.
(along with some of the later spoilers from my post from ch.4 as well)
