The way I interpret this is crazy I feel like he thought he was only that protective and such because he's pregnant not because of Euihyun, then how would he treat him if his not pregnant...
Or the way the panel draws MC black transfer to ML like the one that transfers to him is him not forgiving himself and the way MC in the beginning wants to end everything including himself. Overthinking!!!! let them have peace!!!!!Σ(  ̄□ ̄||) LET THEM JUST HEAL AND LOVE!!!
