hey guys I really need help in finding this one BL manga where the mc transmigrated as this prince I think and he decided to help the hero level up then the hero slowly fell for him

there was this chapter where the prince got affected by a spell that made him technically dead but he was still conscious (it was supposed to be the og love interest who gets thru this plot point) and then their party's mage (? she was a girl) suggested they go to the church to try and revive the prince
