I loved when they kissed each other when they were adults in kid's bodies! I also loved how they had an early love in their childhood in the prev life... authors like to pretend to make teen characters pure and innocent but nahhh this author knew what she was doing XD

ML while sweet and madly in love, is too overbearing in the MC's opinion. she loves him but also can't accept his scheming behaviour to keep her away from kiss scenes/bed scenes or overall emotional contact with men in her movies/shows. He interfered with the career that she loved, while on one hand where she couldn't see he fiercely protected her and sheltered her from various situations like slander/assault/shaming etc. In my opinion, it's very unfair to have such expectations from her yet he himself did participate in kiss scenes etc. Even if he never did those underhand schemes she felt were too much and out of hand. She loved him crazily but his love also became a burden to her. All this is just mentioned in a few lines scattered in the novel so it's not angsty but piling them up together makes it seem worse... IMO even if this was a bit unpleasant I loved it for how much of a realistic problem it was for a couple in the entertainment circle, so I truly hope that they can tackle this in the second life. But to be honest, as much as I love the MC being so dedicated to her career, I wish she'd just prioritize their relationship more in this second life. After all, she's experienced acting for a majority of her previous life as well as from age for in her second life. That's 40+ years... enough of a struggle no? but anyways who am I to judge her character?

edit: what I thought was an obstacle, actually wasn't. The ML improved from the first life and the MC also seemed to have made some concessions. The MC and ML are not completely op cuz they are reborn the ML especially but he did his best. the MC only ever wanted to shine bright and be acknowledged as good enough to stand b ml's side.
