A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

The Soaring Dragon Continent is a world of summons, you can only become strong if you become a summoner! Yue Yang, an average high school boy, was suddenly transported into this world. When he woke up, he was greeted with a lot of worried faces and found out that he had assumed another person’s identity. Turns out he’s the good-for-nothing third son of the Yue Family, who had just recently drowned himself because of a failed engagement. Unlike the third son of the Yue Family who was useless in summoning, Yue Yang succeeded in making a contract with a summoning grimoire on his first try, even when the other guy failed for the past fifteen years. Others would have a headache making contracts with beasts afterwards, but countless beasts tried to gain favour with Yue Yang instead, acting like a good kid before him.

Jiang Chengxuan accidentally traveled to the world of cultivating immortals, and accidentally obtained the inheritance of cultivating immortals.

However, the aptitude is really low, and he has been practicing hard for a hundred years, but he still cannot be promoted to the foundation building state.

Just when he was disheartened and silently came to a mortal city, ready to end his life here, Goldfinger finally arrived belatedly.

It is detected that the host has achieved the achievement of cultivating immortals for a hundred years, and I hereby reward one longevity fruit, which can increase one’s lifespan by serving it.

The next achievement task is now posted.

Ask the host to clear the level a hundred times. After completing it, you can achieve the achievement of breaking through the level one hundred times, and you can get one chance to successfully clear the level.

Ding!

Ask the host to complete a hundred times of spell practice, and if you achieve it, you can get a jade talisman for the inheritance of the perfect spell.

Ask the host to complete a hundred times of exercise achievements, which can improve the root bone.

Ask the host to complete the achievement of making talismans a hundred times…

Ask the host to complete a hundred enlightenment achievements…

Ask the host to complete a hundred alchemy achievements…

Ask the host to complete a hundred poisoning achievements…

Please host…

Unknowingly, when Jiang Chengxuan heard the prompt from the system again, he was told that there is no achievement worthy of you to complete, because your existence itself is already an achievement that can never be surpassed.

The year he was fifteen, Ling Ke realized he was gay, and that he fell in love with a hot guy the same gender he was! Ling Ke spied on the other’s online friend group, payed attention to that person’s every move, and privately, started his fanatical fanboying actions. Unfortunately, the hot guy he liked was someone who changed girlfriends like he changed clothes, a pretentious and straight male.

A few years later, Ling Ke and the hot guy he was secretly in love with got into the same university and became good friends. In order to prevent his beloved from hating him, Ling Ke repressed his true feelings and forced himself to pretend to be a 24k, pure gold straight guy.
……

Having high-spec looks, Qi Feng was a networking expert, but in order to preserve his all-around shining and popular hearthrob image, he always hid his true sexuality, that he was gay. He got himself (fake) girlfriends all throughout school, literally playing himself into being branded as a skirt-chaser.

Until one day, he met his true love. The other looked delicate and gentle, cold and out-of-reach, as if the ideal lover he’d dreamed of in his heart.

Except, there was just one thing. That guy also looked completely straight……

In short, this is the love story of two scared, in-the-closet gay guys pretending to be straight while mutually trying to feel the other out.
