The second one is Eigyou Nika! i think

for two yaoi mangas I've once read but forgot the titles.
1) There was a once rich now poor boy who had a one night stand with a stanger. He wanted to forget all about it and changed his appearance. After several years they met eac h other again and the stranger immediately recognized him again.
2) Two coworkers who get along well. One is secretly in louve with the other. The other seem to like him very much. It's always a fluffy and funny atmosphere about them (is still ongoing) I only remember that one was tossing the other into the water to force him to stay at his hous overnight.
Can anyone help?
