Hi! I'm helping a friend look for some manga. I cannot remember reading any manga that went like these. Synopsis below:

The first is about a man who bumps into a guy on a train who he thinks is his old lover. The old lover was basically using the man for his money. The guy feels kind of guilty for being the replacement of the old lover. In the end they both meet on the train again.

The second manga is about two childhood friends who were neighbours. One of them was rich and lived in a mansion and the other one lived in a shack. When they grew up, the rich kid traveled to America while the poor kid ended working in a dormitory. The rich kid comes back his friend etc.

Please help me out if you know! Thank you very much 😀 !
