I forgot to add the top husband candidates.
For Yoshi, I think the best choice would be 1)Kol, then 2)Nasir, 3)Zed, 4)Razix, and 5).Loro
If for me personally, then: 1) Zed 2) Nasir 3) Razix 4) Kol 5) Loro
....
Spoiler with an explanation if you're interested in why I arranged it this way.
1) Kol. According to the plot, it is more logical and more right for Yoshi to be connected with Kol. Kol gets more exposure than others (in other candidate routes, he's more of a problem/obstacle to the relationship; he's not discussed or talked about at all). In his relationship with Yoshi, he finally realizes what's important to him and that he could have always acted differently (even though Yoshi's tirade about being afraid of killing a pirate was nonsense). Yoshi's choice affects Nasir's relationship with Kol leading them to a familial-friendly relationship rather than one-sided love (Which still seems like a fluid feature to me, depending on Nasir's preferences in other routes). For me personally, he wouldn't have been a candidate, since under Yoshi's conditions, I would have been intimidated and would have had minimal contact with someone who rules through fear. Nevertheless, I passed his route first.
2) Nasir. Yoshi and Nasir are two engineers and have a kinks on each other. The only problem is that their relationship revolves around each other, separating them from the rest of the crew. Personally, Nasir wouldn't be such a good fit for me due to his controversial kinks and occupation, but nevertheless, he's similar to Razix in his flirting without the gaslighting.
3) Zed. A real sniffer. But seriously, none of this would have happened without imprinting, since Yoshi's line of work is different from Zed's, and the second always tries to protect the first when the first doesn't need protection and can protect himself. Zed would be perfect for me personally, since I like his personality and his needs. He's also the cutest one here.
4) Razix. He's too vulgar for Yoshi. Yoshi and Razix's relationship in the story was almost a disaster when Razix decided to jump ship with Yoshi. What's a crew without a pilot? However, Yoshi changes Razix's nature, as he switches from spontaneous affairs to imprinting. At the time, it seemed to me that Razix was better suited to the other candidates' routes. He wouldn't have been right for me, although he could have convinced me to have an affair.
5) Loro. Well, he didn't even appear that often in his own route, but nevertheless, relationship with him was almost the only one that lasted longer than with the others. I finished him last. For both me and Yoshi, he seems more like a father figure or a mentor. Yoshi's line of work doesn't intersect with his at all, nor does mine. When his wife was mentioned in the story, I felt terrified.
