I mean if you think about it, it's either that or Suika is condened to be single forever and what not because those who were her age will now be too kids for her and those that are closer to her age were... too old for her
I mean realistically if she's 16 now she might be interested in being with someone at some point but it'd be weird since everyone she knows she doesn't have that relationship with them
but really, anyone from the group "could" work better than Senku, that's... first of all Senku gives no fucks about that, second of all, their relationship and Suika's feelings are nowhere near that area
2) more recent series', although I can't think of any others in SJ because I'm not on top of it like I was, have had more LGBT representation in a serious non-comedic manner
Stay away from reddit, they are definitely talking about Suika and it's eugh
