What's Wrong with Kissing Your Best Friend?

On the first day after transmigrating into a book, Lin Mo nearly drowned, and his System got soaked and broke. He had no idea what kind of book this was or what character he had become. Lin Mo: Then I'll just treat this like a high-freedom open-world game! He seemed to have lucked out and become a good-for-nothing rich second-generation heir. All he had to do was lie flat, eat, drink, have fun, and enjoy a life of carefree luxury. Unfortunately, the good times didn't last. One day, a young man about Lin Mo's age showed up at the house, claiming to be the real young master who had been living away from home. Only then did Lin Mo's parents reveal that he wasn't their biological son, but a fake young master. Lin Mo was actually relieved. He had transmigrated here, too, so he felt a bit guilty about sitting back and enjoying the good life. He was about to take his leave when, at the worst possible moment, the System suddenly came back online and began popping up plot details out of nowhere: [...You can't bear to give up your lavish lifestyle, so you try to seduce the real young master. On the very first day he returns home, you boldly and wantonly kiss him in front of everyone...] Lin Mo: "...Huh?" This kind of ridiculous behavior was obviously a cannon-fodder character setup! What good ending could a cannon-fodder possibly get? Lin Mo's eyes shifted to the good buddy beside him, who was just as idle as he was, a perfect match for his slacker ways... No, they shared the same interests. He was a rich young heir, and the one who had fished Lin Mo out of a pool of wine on the day he arrived: Lu Xingyuan. With the System's warning alarms blaring, Lin Mo had no choice but to plant a kiss on his good buddy's handsome cheek. Lin Mo: "It never said which real young master. You tell me, is this one real or not?" [...] The System had just repaired 1% of itself, and now its CPU crashed again. Afterward, Lin Mo comfortingly patted Lu Xingyuan on the shoulder. "What's wrong with a good buddy giving you a kiss?" Little did he know that those words were the beginning of the trouble. Later, Lu Xingyuan not only took him seriously, but even started extrapolating from it! "What's wrong with good buddies hugging?" "What's wrong with good buddies sleeping together?" "What's wrong with good buddies doing..." Lin Mo threw a pillow at him. "Shut up! Say another word and I'll kill myself!" * Lu Xingyuan had transmigrated into a melodramatic novel about a real and fake young master, as the male lead. As a straight man, he was deeply troubled, so he deliberately turned himself into a good-for-nothing, frequenting the company of beautiful women and indulging in wine and pleasure... including becoming good buddies with that useless fake young master. He refused to believe that someone this depraved could still be the male lead. But the very day the plot prompts appeared, he found out that his good buddy was the protagonist, and... his good buddy was really sweet. Lu Xingyuan: Being the male lead isn't so bad after all! He immediately dropped his playboy act, reinvented himself, and insisted on reclaiming the role of male lead. But after enduring the pain of missing Lin Mo and fighting his way through career struggles and family feuds, he found Lin Mo and the real young master getting along far too intimately. Lu Xingyuan exploded and pinned Lin Mo against a corner. "Do you kiss him because you're good buddies, too?" Still dazed from the kiss, Lin Mo stared blankly. "Huh? That's my brother..." His brother on the same household register! Who would be good buddies with a wild one like you... Theme: True love is right beside you
