The amount of people who want them to break up is ridiculous
Honestly it's just two people
A Raging Yandere Brocon with Poison Magic
And a Raging Sadist Tsundere Lesbo with Healing Magic (who to be fair has yet to SEE "Hubby" yet, all she knows is she hates him for "Stealing her Yui" without realizing her behavior TURNED Yui off of her LONG BEFORE! That wasn't RIVILARY back then like she thinks! That was "Well Jobs done, LET US NEVER MEET AGAIN!" But not seeing Ryouta leaves up to how she'll feel about him)
Anyone who cares about the couple are encouraging, and Draco the Paladin is the DEFENDER of their marriage because Yui is her Role Model she looks up to and Ryouta is a good man that has ever been kind! Of COURSE as a Paladin she would defend their "perfect marriage" from "interlopers" who'd want to ruin it for SELFISH reasons who she's long pointed out she's "The only SANE WOMAN of the Party!" (she's right in that Juju is a DANGEROUS Variable because she PURPOSELY sabotaged the party IN THE DUNGEON just to make an attempt on Yui! Normally if one doesn't KILL the Party Traitor there and then, they OBVIOUSLY will kick them out, even if she never planned on Ryouta and Draco being harmed, and Draco was an afterthought to Juju as a reminder! She still endangered them trying to kill Yui! And I'm sure her HERO WORSHIP of the Hero's Party is further damaged as she suffers "never meet your Heroes in real life LOL)
Honestly we still haven't seen "The other members" yet, so who knows how they feel, hopefully to balance the scales, their like Draco (Happy Yui found happiness and SUPPORT the marriage! Maybe one ACTS in place of "the big brother" and sees if RYOUTA is worth of her, but only in that vein and DOES see what Yui sees in Ryouta and supports it full on!)
There's also the chance Ms. Saintess might go BI (As in she falls for Ryouta and tries to INSERT herself as "The Mistress" in their marriage, the UNOFFICIAL other wife! Even if he has a HAREM Party, Juju is regulated to "Little Sister do not touch" and Draco is mutually "Just a friend and Comrade")
