CheolMiae parallel... I hvnt reread aslfua in a ling time, but perhaps these would work:
- The way each of them has influenced the other's life so much? Both b4 and after they met again in middle school.
- The way both keep yearning for the other without the other being aware and believing that they alone feel that strongly for the other - this might sound like it's for b4 Miae and Cheol ended up confessing to each other after the laser tag game, but I think even after that, there's a gap coz both chose to hide away their feelings for each other using the bet.
- The way they always try to do the best for each other, even if it ends up often hurting the other. For example, even tho Cheol wished to meet Miae b4 finally moving into her neighbourhood, he decided to keep a distance from her coz of fear of his past catching up to him, which often and still make Miae believe that he hated her. Similarly, Miae also started internalising her issues more from Cheol and eventually when mole guy threatened ruining Cheol's time in school, she started hiding it even more, to the point where she said hurtful things to him.
