The female love interests in both mangas are more foward with their feelings, falling just shy of confessing. The MC in both often wonders why they're receiving this attention and puts himself down. Both follow a story-arc of character growth where the characters begin to gain courage and think better of themselves as they fall deeper in love.
These two mangas are essentially the exact same manga - no other way to describe it. Both are isekai where the MC has total knowledge of the world and immediately outclasses the strongest adventurer in the world with their knowledge. If you catch up to the latest release on one and still need a fix, read the other!
