Unironically Lamy, people who say she is menhera just don't watch her. She's dependent on her fans to the extent but she has pretty normal social life, really close family ties, maybe not a lot of friends but she still goes out from time to time. She is likely really attractive and pays attention to her appearance and health a lot (beauty salons and buying trendy clothes / goes to doctors if something's wrong with her health, tries to maintain at least somewhat healthy lifestyle). Lamy is doing GFE, but not in a manipulative way, her fanbase loves her a lot but she genuinely feels affection for them too. Before you say "keep believing, paypig", consider this:
She does egosearching A LOT and likes few things more than praise from fans. Sometimes goes on likes/replies spree on twitter, sometimes visits her free chat. And it's not like she goes in menhera fits if something upsets her, she seems to only pay attention to positive comments that motivate her to push forward.
Lamy has an amazing mentality and is almost always able to look at the positive side of things. She supports her fans as much as they support her, her "yoshi yoshi, ganbatte" are genuine. She has stated from the debut that she sees her main purpose as a streamer in having healing/motivating effect on people, so that they could come home after a busy day, relax and listen to someone who tries to encourage them.
Her signs, I mean when she signed her limited merch, are really personal and thought out, Lamy spent a fuckton of time on them and tried to write heartfelt messages for everyone. She also remembers a lot of people who donate and/or reply to her tweets often.
Yandere meme is just a meme. When she's sincere she always talks about how fans should consider their health and well-being first and go to sleep on time, donate only if it won't affect their situation heavily etc.
And besides GFE, Lamy does many more things. When it's not ASMR (I love you, yoshi yoshi etc., what else do you say during these anyway) or drinking streams (where she tends to go in "tell me you love me" mode) she's like a mature supportive onee-san in zatsudans. Or a dork friend in games/watchalongs. Even if she does play up GFE aspect occasionally, I don't care because she's fun to watch and support for many other reasons.
LAMY LOVE
