it seems the girls are planning o accept but they have some plan in mind, also that girl is so stupid, if she liked the MC that much she should be the first to leave the guild and follow him insted of doing stinky stuff from behind the scenes hoping the MC would return

The guild master is stupid. He sold out the top party of their guild to the enemy's recruitment plan thinking that it's not possible they would actually accept the offer. This is very dumb because what if the girls decide to accept the offer? The Magic Tree guild would essentially be decapitated of their excellent latest generation team and the enemy, that's already failing and having mass layoffs will get an instant new star team. Really really stupid stuff.
