uhh i think you're forgetting something, they died as a highschooler, around 18 years old as they claim to, the 25 years old part is plus with the time they were reborn and grow up into a 5 years old child.
So tbh, they still a highschooler that properly minding silly stuffs in peaceful world, can't blame them for acting this way.
Are the twins really 23? Because they are stupid for their age, they are really stupid that sometimes it prevents me from really appreciating this manhwa ╥﹏╥
