It's not that I'm totally against it, but the syndrome of romance comics have everyone pair up ... including the grandmother's dog ... is kinda trite ^^
Well, I would like to add that the couples are being set up fairly early and strongly telegraphed. It's not like everyone gets into relationships. Most of Saku's and Kasumi's friends didn't for example. Neither did the dorm girl or Saku's other siblings.
If a pairing is going to happen, Yukiko doesn't obfuscate that intention for long. Hina and Fujiho are actually the least build up until now and there is no real change in sight, but it still seems blatant that she intends to go there eventually.
