That's actually pretty common for kids, even if a "cute girl" follows you, you only care of games and cartoons at that age.
They are like 13-15 yo in middle school, that's about the age boys gets interested in love... so even if he "loved" Lilliel since elementary school, he still confessed to a girl he simped for, but the rejection and the resulting bullying made him regret it so much he choosed to only trust 2D world.
p.s. Honestly I don't even know why I'm defending this manga, probably I only like to create discussions xD
