Maybe he time travelled due to one of the esper's power and met the kid seme?
But then,they checked for the bond n he's not the one? Hnmmmmmm idk just my opinion lol

SPOILERRR**
He did time travel, but through the rift in the gate where uju hyung "disappeared" while fighting the anti-espersumt leader(? I forgot the name lol) I suggest u to read the novel, it's very emotional! I cried more than once ugh They're both such green flags ☹
And about the bond, it's because ML is an S-Class mental esper, so he subconsciously made the rejectrion through both of them (kinda powerful ngl) the novel explained more about it! It's more like his soul and mind isn't in sync..?
I usually ship those two but as the plot progress ,I felt like their vibes are more like brotherhood rivalry than shonen ai instead. Same like Xavier and Lloyd.
Wdymmm it was always brotherhood!!!!
I know. It's not even bl or shonen ai. Just how I depict some brotherhood sometimes
