there are plenty of novels where the guy protects/stands up for the girl but how often does the reverse happen? send recommendations! No BL or GL
Sevens, there's both WN and LN version. Yoraikun finished translating the WN. LN is being done by someone else.
It's fine I guess, the bringing back the tech stuff is not bad but not particularly good and the relationship is also fine. Overall somewhere between 3.5 to 4. Strictly my opinion though.
Crossing to the future its not easy to be a man. The ml hasnt really gotten deeply involved yet. Still merely one of her buddies. She is still their big boss tho. And she doesnt think of the ml romantically so it might not fit what you are looking for.
Battle Through the Heavens (Female lead is secretly protecting the Mc until he is strong enough to survive on his own) The Legendary Moonlight Sculpture (Female lead saves the Mc's ass plenty of times, even sacrifices herself at times)
https://www.novelupdates.com/series/reborn-i-became-a-male-god/ Mc is so gentle and decent, he know how to protected girl. he is very loyal and DOTING to female lead
Perfect Secret Love: The Bad New Wife is a Little Sweet fits the bill too. Spoiler: Why? Ye Wan Wan, the female protagonist helds on to Si Ye Han's, the male lead's thigh so thight she became overprotective of him.
